What is onion domes in moscow?

Onion domes are a prominent feature in the skyline of Moscow, Russia. These distinctive domes are typically made of wood or metal and are shaped like an onion bulb, with several layers stacked on top of each other.

Onion domes first appeared in Russian architecture in the 15th century and became more prevalent in the 16th and 17th centuries during the reign of Ivan the Terrible. They were often added to the roofs of churches and other religious buildings, symbolizing the connection between heaven and earth.

Today, many of Moscow's most famous buildings feature onion domes, including St. Basil's Cathedral, the Cathedral of Christ the Savior, and the Church of the Ascension. Many of these structures have undergone extensive restoration since the fall of the Soviet Union, which saw the destruction or closure of many religious buildings.

Onion domes are an important part of Russian cultural heritage and continue to be a source of fascination and inspiration for architects and designers around the world.
