In the Gothic quarter of Barcelona - the historic city center, where most of the buildings and streets have historical significance, is a small square, called the Plaza Ramon Berenguer the Great. This square is named in honor of count Ramon Berenguer III, who ruled from 1096 at year 1131. Ramon Berenguer III belonged to the same dynasty, that of count Ramon, who in 1058 G. on the ruins of a Basilica in Barcelona laid Romanesque Cathedral.

On the square stands the majestic equestrian statue of the famous Barcelona's count Ramon Berenguer the Great, the construction of which was engaged by the famous architect Josep Limon. The biggest attraction of the square is the ancient Roman wall in the fourth century B. C., which serves as the Foundation for an elegant and austere Church - the chapel of St. Agatha.

The chapel of St. Agatha, the building of Gothic architecture, built in the FOURTEENTH century, was part of the Royal Palace. Its octagonal bell tower completes eight triangular pediments and resembles a Royal crown. The chapel of St. Agatha is currently part of the Museum of history of Barcelona.

Preserved the towers have already joined in later buildings, and until the mid-twentieth century to the Roman wall literally were stuck living at home. By 1950, the Roman wall parted with their tenants, and Plaza Ramon Berenguer the Great acquired its present appearance.
