Smithsonian Day

Smithsonian Day is dedicated to the Smithsonian Institution and takes place on September 18. On this day, museums, zoos, exhibition centers, and many other cultural institutions welcome visitors. People have a unique chance to explore an incredible variety of exhibits and relics, some dating back hundreds or even thousands of years.

History

The Smithsonian Institution is a vast research and cultural center that began developing in the mid-19th century. The project was envisioned by British scientist James Smithson. Construction began in 1849 and was completed six years later.

In 1846, the U.S. Senate officially endorsed the creation of the institution, providing government support. Many talented specialists from various fields joined the Smithsonian. In addition to research, the institution preserves thousands of relics and collections, which are expanded every year. It is often called the “nation’s attic,” as it holds over 150 million items from different eras.

Today, the Smithsonian is a massive complex that includes 21 museums, a zoo, and nine research centers.
