Spain's San Martín de Teruel Tower is an Aragonese Mudejar structure that was added to the UNESCO World Heritage List in 1986. A stone base was constructed during a 16th-century renovation after it was built in 1316.

It was constructed between 1315 and 1316 and renovated by Quinto Pierres Vedel between 1549 and 1551. Quinto Pierres Vedel removed terraced homes from the area in front of the tower to create a square and added an ashlar reinforcement to the base of the tower to repair and prevent further deterioration of the lower part, which had been severely eroded by damp. During the Spanish post-war period, Manuel Lorente Junquera again intervened on the tower, replacing ceramic pieces with a more muted tone than the original ones. Ricardo Garca Guereta made a significant restoration in 1926. A thorough restoration of the interior and exterior, as well as the reconstruction of the former entry beneath the tower, took conducted between 2002 and 2007.

It is situated across from the Calle de los Amantes in the Plaza de Pérez Prado. It is a brick tower-door with glazed ceramic ornamentation, similar to other towers in Teruel's capital, beneath which the Andaquilla slope passes. There is a pointed vault that leads to the tower's base. The first part only shows three of its sides since the fourth is affixed to the Baroque-era San Martn church.

With two concentric square towers separated by staircases, the tower mimics the design of an Almohad minaret. Three storeys that are placed on top of one another make up the internal tower.

Undersecretary of Public Instruction Carlos Castel y González de Ameza (1873–1927) "began the process of recognising the Mudejar towers of San Martn and El Salvador national monuments."

In 1986, UNESCO designated the Teruel city's Mudejar monumental complex as a World Heritage Site.
