1. The National Museum in Belgrade, also known as Narodni Muzej u Beogradu, is the largest and oldest museum in Serbia. It was founded in 1844 and has been housed in its current building since 1903.

The museum’s collection features over 400,000 objects, including archaeological artifacts, historical objects, artworks, and natural history specimens. Some of the most notable exhibits include prehistoric artifacts, ancient Egyptian and Greek art, medieval Serbian art, and a comprehensive collection of European art.

One interesting fact about the National Museum is that during World War II, many of its valuable artifacts were hidden to protect them from damage or theft. Some of these hidden treasures were discovered years later in various locations around Serbia.

The building itself is an impressive architectural landmark, designed in the neoclassical style. In recent years, the museum underwent extensive renovations and reopened to the public in June 2018, after being closed for 15 years.
