Merrion Square is a Georgian garden square located in the heart of Dublin, Ireland. It was designed and developed in the late 18th century by the famous architect James Gandon, who was also responsible for many other prominent buildings in the city, such as the Custom House and the Four Courts.

The square was named after the Earl of Merrion, who owned the land on which it was built. It was laid out in the classic Georgian style, with four sides of beautiful, terraced houses and a central garden. The garden was originally intended as a private amenity for the residents of the square, but it was later opened to the public.

Merrion Square quickly became one of the most prestigious addresses in Dublin, attracting wealthy merchants, lawyers, and other professionals. Among the notable residents of the square were the playwright Oscar Wilde, who lived at number 1 Merrion Square for a time, and the mathematician William Rowan Hamilton, who lived at number 36.

Today, Merrion Square remains one of the most beautiful and iconic parts of Dublin, attracting tourists and locals alike. The square and its surrounding streets are home to many cultural institutions, including the National Museum of Ireland and the Irish Writers’ Centre, as well as many shops, cafes, and restaurants.
