Mount Rushmore National Memorial is located along the northeast edge of what is known as the Harney Peak Granite Batholith in the Black Hills of South Dakota. A batholith is a geologic feature that formed by the cooling of a large igneous body of magma below the earth's surface; if a similar igneous body reaches the earth's surface, it would form a volcanic feature such as a lava flow. The Black Hills magma was emplaced into the older "host" mica schist rocks during Precambrian time, approximately 1.7 billion years ago! Source: National Park Service
There are many. A great example, however, is Mt. Rushmore; the likenesses of the presidents are carved in granite, a coarse-grained intrusive igneous rock.
If you go to Bruges, many of the structures are of igneous rock. Also true of medieval castles (some, no specifics.) The High Street in the UK utilizes granite and diorites, but that might be too specific. Ultimately, it is very stable, ut not easy to work with.

The faces of four US Presidents: George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt, are carved into Mount Rushmore National Memorial in the Black Hills of South Dakota. Another mountain monument is being carved into Thunderhead Mountain in the Black Hills of South Dakota. The face on that monument is that of the Oglala Lakota warrior, Crazy Horse. The monument is part of the Crazy Horse Memorial.

Mount Rushmore is a national monument in the Black Hills mountain range of southwest South Dakota. Mount Rushmore features 60-foot sculptures of the heads of U.S. Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.
Well, Mount Rushmore is the mountain; that the landmark Borglum carved shares the name is perhaps shorthand. The Black Hills is the geologic range. It is located in the southwest corner of South Dakota, close to the town of Keystone, and is carved into the northwest face of Harney Peak.
Carving was done by using dynamite to blast away more than 90% of the rock. Once there was about 3 to 6 inches of rock left to remove, they used a technique called "honeycombing", drilling holes very close together, which weakened the granite so that it was easier to remove. After the honeycombing, the granite was smoothed with a hand facer or a bumper tool, creating a surface as smooth as sidewalk.
The Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore (Lakota Sioux name: Six Grandfathers) near Keystone, South Dakota, in the United States. The carving started in 1927, and ended in 1941.
About 641 feet wide and 563 feet high of the Crazy Horse Monument is being carved.
