Plaça de la Font, Neoclassical square in Tarragona, Spain

Plaça de la Font occupies a quarter of the arena of Tarragona's Roman circus, on the site of the circus's central spine. The square is presided over by the neoclassical facade of the city hall on its south side, and a subterranean parking garage lies beneath it. Its facades show diverse decorative solutions, the result of slow, piecemeal occupation.

The square occupies a quarter of the arena of Tarragona's Roman circus, specifically the site of the spina. After antiquity it decayed into a livestock yard called El Corral, later hosting a daily market until 1915. In 1363 Archbishop Pere de Clasquerí had a 47-metre well dug; it was also called a "font", giving the square its name. The neoclassical City Hall facade dates from later reforms, including Josep Oriol's 1839 project.

The name comes from a 47-metre well built in 1363 by order of Archbishop Pere de Clasquerí, also called a "font". The square is a casteller stage: on 24 June, the first Sunday of the Santa Tecla festivities and 23 September, the city's colles raise their human towers here.

The square sits in the Part Alta, a short walk uphill from the city's lower quarters, and is reached on foot through the surrounding old streets. An underground car park lies beneath the square, built amid controversy over possible damage to Roman remains. The square is the setting for casteller performances on Sant Joan (24 June), the first Sunday of the Santa Tecla festivities and 23 September.

The square's name comes not from a fountain but from a well built in 1363 by Archbishop Pere de Clasquerí, 47 metres deep, which was also called a "font". The 1827 monumental fountain by Pere Anton Verderol and Vicenç Roig disappeared in the mid-19th century. Three residents' birth or home addresses are remembered: poet Joan Antònio i Guàrdias at number 53, illustrator Ricard Opisso i Sala at number 10, and politician Marcel·lí Domingo i Sanjuan, born at number 6 on 25 April 1884.
