Cass Gilbert in the context of Arkansas State Capitol

The Minnesota State Capitol is the seat of government for the U.S. state of Minnesota, in its capital city of Saint Paul. It houses the Minnesota Senate, Minnesota House of Representatives, the office of the attorney general and the office of the governor. The building also includes a chamber for the Minnesota Supreme Court, although court activities may also take place in the neighboring Minnesota Judicial Center.

There have been three State Capitol buildings. The present building was designed by architect Cass Gilbert and completed in 1905. Its Beaux-Arts/American Renaissance design was influenced by the 1893 World's Columbian Exposition in Chicago, and by McKim, Mead & White's Rhode Island State House. From 2013 to 2017 the building underwent an extensive restoration. This included replacing existing infrastructure; adding new mechanical systems; replacing or repairing tens of thousands of pieces of marble on the exterior; cleaning historic paintings, murals, and sculptures; and adding safety and accessibility features.

The Supreme Court Building houses the Supreme Court of the United States, the highest court in the federal judiciary of the United States. The building serves as the official workplace of the chief justice of the United States and the eight associate justices of the Supreme Court. It is located at 1 First Street in Northeast Washington, D.C. It is one block immediately east of the United States Capitol and north of the Library of Congress. The building is managed by the Architect of the Capitol. On May 4, 1987, the Supreme Court Building was designated a National Historic Landmark.

Designed in the neoclassical style, the proposal for a separate building for the Supreme Court was suggested in 1912 by President William Howard Taft, who became Chief Justice in 1921. In 1929, Taft successfully argued for the creation of the new building but did not live to see it built. Physical construction began in 1932 and was officially completed in 1935 under the guidance of Chief Justice Charles Evans Hughes, Taft's successor. The building was designed by architect Cass Gilbert, a friend of Taft.

The Woolworth Building is a 792-foot-tall (241 m) residential building and early skyscraper at 233 Broadway in the Tribeca neighborhood of Lower Manhattan in New York City. Designed by Cass Gilbert, it was the tallest building in the world from 1913 to 1929, and it remains one of the United States' 100 tallest buildings as of 2024.

The Woolworth Building is bounded by Broadway and City Hall Park to its east, Park Place to its north, and Barclay Street to its south. It consists of a 30-story base topped by a 30-story tower. Its facade is mostly clad with architectural terracotta, though the lower portions are limestone, and it features thousands of windows. The ornate lobby contains various sculptures, mosaics, and architectural touches. The structure was designed with several amenities and attractions, including a now-closed observatory on the 57th floor and a private swimming pool in the basement.

The Bayonne Bridge is a steel through arch bridge that spans the Kill Van Kull between Staten Island, New York, and Bayonne, New Jersey, United States. It carries New York State Route 440 and New Jersey Route 440, with the two roads connecting at the state border at the river’s center. It has the sixth-longest steel arch mainspan in the world, the longest in the world at the time of its completion. The bridge is also one of four connecting New Jersey with Staten Island; the other two roadway bridges are the Goethals Bridge in Elizabeth and Outerbridge Crossing (which also carries Route 440) in Perth Amboy, and the rail-only span is the Arthur Kill Vertical Lift Bridge, all of which cross the Arthur Kill.

The original four-lane roadway was designed for the Port Authority of New York and New Jersey by Swiss master bridge-builder Othmar Ammann and architect Cass Gilbert. Completed in 1931, it included a walkway, and offered 151 feet (46 m) of vertical clearance above the water.

The Alexander Hamilton U.S. Custom House (originally the New York Custom House) is a government building, museum, and former custom house at 1 Bowling Green, near the southern end of Manhattan in New York City, New York, United States. Designed by Cass Gilbert in the Beaux-Arts style, it was erected from 1902 to 1907 by the government of the United States as a headquarters for the Port of New York's duty collection operations. The building contains the George Gustav Heye Center museum, the United States Bankruptcy Court for the Southern District of New York, and the New York regional offices of the National Archives. The facade and part of the interior are New York City designated landmarks, and the building is listed on both the New York State Register of Historic Places and the National Register of Historic Places (NRHP) as a National Historic Landmark. It is also a contributing property to the Wall Street Historic District, listed on the NRHP.

The Custom House is a seven-story steel-framed structure with a stone facade and elaborate interiors. The exterior is decorated with nautical motifs and sculptures by twelve artists. The second through fourth stories contain colonnades with Corinthian columns. The main entrance consists of a grand staircase flanked by Four Continents, a set of four statues by Daniel Chester French. The second-story entrance vestibule leads to a transverse lobby, a rotunda, and offices. The rotunda includes a skylight and ceiling murals by Reginald Marsh. The George Gustav Heye Center, a branch of the National Museum of the American Indian, operates on the ground and second stories, while the upper stories contain U.S. government offices.
