Durango is a city and municipality of the historical territory and province of Biscay, located in the Basque Country, Spain. It is the capital city of Durangaldea, one of the comarcas of Biscay. Because of its economical activities and population, Durango is considered one of the most important cities in Biscay after the ones that compose the conurbation of Greater Bilbao.

Durango has 28,618 inhabitants (2012). The town is crossed by three rivers (as illustrated in the town symbol). The Ibaizabal river is the main river, and lies in the middle of its wide valley, with the scenic Urkiola mountain range and natural park to the south. The most important peak is the majestic Anboto (1,331 m (4,367 ft) in elevation). In addition, inside the town stand out two mountains: Pagasarri mountain (838 mts.)and Neberondo (453 mts.).

There are many differing opinions about the origin of the name Durango. Basque linguist Alfonso Irigoyen has suggested its origin to be in the name Duranco, probably used in the early Middle Ages. Other authors suggest the name to be a derivation of Urazango or an evolved form of Padurango. In the confirmation of the town's fuero it is referred to as Tavira de Durango; Tavira was probably the primitive name of the settlement and Durango the name of the region surrounding it. Until the 16th century, the town was known as Uribarri de Durango, Uribarri being Basque for "New town".

Main sights include:

• The Kurutziaga Cross. It was built between the late 15th and early 16th century. It tells a story and it has a gothic style with a clear Flemish, German influence.
• Baroque Santa Ana's Arch, designed by local architect Juan de Herdoiza (18th century) for the now disappeared line of walls. The arch was constructed to symbolise the town gates, through which the King was required to pass when he visited.
• Mikeldi idol, of pre-Roman times, representing a quadrupedal animal.
• Lariz Tower is an urban palace which was built around the end of the 15th century. It was renovated in 2009 and, currently, it is the Tourist Information Office of the town. It is believed that the Queen Isabella Catholic stayed overnight when she visited Durango in order to swear the regional laws (fueros) and those of the Merindad de Durango. In the building there are decorative elements of the final Gothic such as large windows of seat or heights of taste Hispanic-Fleming and others of the Renaissance.
