Republic Square is the central square of Yerevan, the capital city of Armenia. The square was designed by Alexander Tamanyan, an Armenian architect, in 1924, and it was known as Lenin Square during Soviet times. The square has a large oval shape and is surrounded by a number of significant buildings and landmarks, including the National Gallery and History Museum, the Government House, the Marriott Hotel, the Armenian History Museum, and the Ministry of Foreign Affairs.

At the center of the square stands the famous "Dancing Fountains," a beautiful water fountain display that is choreographed to music and light. The fountains were installed in 2007 and have since become a popular attraction in Yerevan, especially in the summertime when the weather is warm.

The square is also known for its rich history and cultural significance, as it has been the site of many important events throughout Armenian history. For example, it was the location of the first public speech given by Armenia's first president, Levon Ter-Petrosyan, following the country's independence in 1991.

Overall, Republic Square is a vibrant and bustling center of activity in Yerevan, with many cafes, restaurants, and shops located in and around the square. It is a must-see destination for visitors to Armenia's capital city.
