Mutriku was founded at the beginning of the XIII century (1209), and was originally a walled town, though little remains of the early fortifications. The town is perched on a slope overlooking the port, and the layout of the old part is typical of medieval hillside towns.
The main artery of the old quarter is "Erdiko kale" or Central Street, which leads from the Lower Square ("Beheko Plaza"), where the first settlement was established, up to the Square of Churruca.
The historic part of Mutriku still maintains part of its gothic layout and boasts houses and palaces dating from the 15th to the 18th centuries which are of great architectural and artistic interest.
In Churruca Spuare are to be found the Town Hall and Galdona Palace. In the street "conde de Motrico" (Count of Mutriku) are Gaztañeta House (known as the House of Churruca) and Zabiel Palace, a worthy example of 16th century architecture and currently used as the Cultural Centre of the town.
A 17th century construction, the Casa Olazarra stands out for its woodwork and its large Coat of Arms. The Montalibet Palace was built in the 18th century. According to local legend, the Tower of Berriatua or "Sulengua" is one of the few buildings that escaped the fire of 1553. Although it has been altered over the years, particular features remain such as como su entrada con arco jerminada, ventanas gemelas con arco conopial y parteluz, así como su remate de modillones.
