Prairie-style homes were made famous by the architect Frank Lloyd Wright. These homes celebrate and complement the natural beauty of the Midwestern landscape with low and long shapes in the floor plan and building elements.
Prairie-style houses showcase:
- Long and low-to-the-ground builds
- Flat or shallow roofs with overhanging eaves
- Thin bricks or stucco exteriors to match the house shape
- Minimalist yet stylized ornamentation
Prairie houses inspired the flat planes and natural elements popular in Mid-century houses.

The American Farmhouse is a simple and timeless style. Farmhouses are designed to be practical first and foremost. They’re common across the US and often showcase regional variations, like wrap-around porches in the South.
Farmhouses have evolved with time and location, but often feature these elements:
- Rectangular floor plan
- Large front porches
- Natural wood and stone materials
- Few and small windows
- Formal front rooms separated from family rooms
Of course, the easiest way to identify a farmhouse is that they’ll often be situated on a large plot of farmland.
Most Dutch Colonial homes you find today are actually from the Colonial Revival period of the early 20th Century. Original Dutch Colonial homes feature flared roof eaves and creative wood and brickwork. They are much more ornamental than classic Colonial homes, though the Dutch Colonial Revival style tends to be more subdued than the original Dutch Colonial homes.
Dutch Colonial Revival houses feature:
- Broad gambrel roofs that are visually similar to barn-style roofs
- Open-floor plans
- Flared roof eaves
- Split doors
The large barn-style roofs are the most identifiable feature of a Dutch Colonial home and even became known as “Dutch roofs.”
Victorian homes were built between 1837 and 1901 while Queen Victoria reigned in Britain. “Victorian” actually refers to multiple styles that vary in influence, but each features ornate detailing and asymmetrical floor plans.
The key features of a Victorian-era home include:
- Elaborate woodwork and trim
- Towers, turrets, and dormer windows
- Steep gabled roofs
- Partial or full-width porches
Victorian homes are all about ornamentation — industrialization allowed these homes to be produced en masse and across a variety of architectural styles.
Mid-century Modern designs are nothing new and have influenced interior design, graphic art, and house styles. Mid-century Modern homes are designed to embrace minimalism and nature. They’re also often modeled to appeal to a futuristic or abstract concept.
Mid-century Modern homes can be identified by their:
- Flat planes and clean lines
- Monochromatic brickwork
- Asymmetrical home layouts
- Nature-inspired interior
- Interior level shifts between rooms
Mid-century architecture is still widely popular today, as are Mid-century Modern interior design and furniture trends.

The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin,[1] Andrew Oliver, and other Founding Fathers of the United States.[2] It is headquartered in Cambridge, Massachusetts.
Membership in the academy is achieved through a thorough petition, review, and election process.[3] The academy's quarterly journal, Dædalus, is published by MIT Press on behalf of the academy.[4] The academy also conducts multidisciplinary public policy research.
The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people."[6] The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commercial sectors of the state. The first class of new members, chosen by the Academy in 1781, included Benjamin Franklin and George Washington as well as several international honorary members. The initial volume of Academy Memoirs appeared in 1785, and the Proceedings followed in 1846. In the 1950s, the Academy launched its journal Daedalus, reflecting its commitment to a broader intellectual and socially-oriented program.[7]
Since the second half of the twentieth century, independent research has become a central focus of the Academy. In the late 1950s, arms control emerged as one of its signature concerns. The Academy also served as the catalyst in establishing the National Humanities Center in North Carolina. In the late 1990s, the Academy developed a new strategic plan, focusing on four major areas: science, technology, and global security; social policy and education; humanities and culture; and education. In 2002, the Academy established a visiting scholars program in association with Harvard University. More than 75 academic institutions from across the country have become Affiliates of the Academy to support this program and other Academy initiatives.[8]
The Academy has sponsored a number of awards and prizes,[9] throughout its history and has offered opportunities for fellowships and visiting scholars at the Academy.[10]
In July 2013, the Boston Globe exposed then president Leslie Berlowitz for falsifying her credentials, faking a doctorate, and consistently mistreating her staff.[11] Berlowitz subsequently resigned.

The United States has 63 national parks, which are Congressionally-designated protected areas operated by the National Park Service, an agency of the Department of the Interior.[1] National parks are designated for their natural beauty, unique geological features, diverse ecosystems, and recreational opportunities. While legislatively all units of the National Park System are considered equal with the same mission, national parks are generally larger and more of a destination, and hunting and extractive activities are prohibited.[2] National monuments, on the other hand, are also frequently protected for their historical or archaeological significance. Eight national parks (including six in Alaska) are paired with a national preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below. The 423 units of the National Park System can be broadly referred to as national parks, but most have other formal designations.[3]
A bill creating the first national park, Yellowstone, was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks), Sequoia and Yosemite in 1890. The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."[4] Many current national parks had been previously protected as national monuments by the president under the Antiquities Act or as other designations created by Congress before being redesignated by Congress; the newest national park is New River Gorge, previously a National River, and the most recent entirely new park is National Park of American Samoa. A few former national parks are no longer designated as such, or have been disbanded. Fourteen national parks are designated UNESCO World Heritage Sites (WHS),[5] and 21 national parks are named UNESCO Biosphere Reserves (BR),[6] with eight national parks in both programs.
Thirty states have national parks, as do the territories of American Samoa and the U.S. Virgin Islands. The state with the most national parks is California with nine, followed by Alaska with eight, Utah with five, and Colorado with four. The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km2), it is larger than each of the nine smallest states. The next three largest parks are also in Alaska. The smallest park is Gateway Arch National Park, Missouri, at 192.83 acres (0.7804 km2). The total area protected by national parks is approximately 52.2 million acres (211,000 km2), for an average of 829 thousand acres (3,350 km2) but a median of only 208 thousand acres (840 km2).[7]
The national parks set a visitation record in 2017, with more than 84 million visitors and set a further record in 2018 with a 0.1% increase.[8][9] Great Smoky Mountains National Park in North Carolina and Tennessee has been the most-visited park since 1944,[10] and had over 14 million visitors in 2021.[11] In contrast, only about 7,000 people visited the remote Gates of the Arctic National Park and Preserve in Alaska in 2021.

Second Empire homes were a modern Victorian-era style that started in France before spreading through the Northeastern and Midwestern United States. Second Empire architecture features similar ornate Victorian trends, though generally offers a simplified Victorian aesthetic.
These elements help identify a Second Empire home:
- Uniquely shaped Mansard Roof
- Decorative window framing and dormers
- Decorative rails or balustrades around terraces and staircases
- Iron roof crest and eaves with support brackets
Second Empire homes are also easy to identify since they’re the only Victorian-era style that often features a symmetrical, rectangular floor plan.
The Royal Exchange in London was founded in the 16th century by the merchant Sir Thomas Gresham on the suggestion of his factor Richard Clough to act as a centre of commerce for the City of London.[1] The site was provided by the City of London Corporation and the Worshipful Company of Mercers, who still jointly own the freehold. It is trapezoidal in shape and is flanked by Cornhill and Threadneedle Street, which converge at Bank junction in the heart of the city. It lies in the ward of Cornhill.
It has twice been destroyed by fire and subsequently rebuilt. The present building was designed by Sir William Tite in the 1840s. The site was notably occupied by the Lloyd's insurance market for nearly 150 years. Today the Royal Exchange contains Fortnum & Mason The Bar & Restaurant, luxury shops, and offices.
Traditionally, the steps of the Royal Exchange are the place where certain royal proclamations (such as the dissolution of parliament) are read out by either a herald or a crier. Following the death or abdication of a monarch and the confirmation of the next monarch's accession to the throne by the Accession Council, the Royal Exchange Building is one of the locations where a herald proclaims the new monarch's reign to the public.
