Qualche cenno sull'argomento:

Piazza Costituzione, initially called Piazza della Maddalena and later Piazza Umberto I, named after the Savoyard king, is surrounded by beautiful houses such as the Palazzo with the Delitala portico. It was built in 1877 on the place where once stood the church of La Maddalena, demolished in 1872 to follow the urban redevelopment project of the engineer Cadolini (Piano d’ornato) which provided for the reorganization of Corso Vittorio Emanule. The square was built during the construction of the first public aqueduct in Bosa. Between 1881 and 1882 was built the big fountain with a red trachyte base on three levels on which stands the marble fountain with four risers with, at the top, a bunch of roses with a central hole for the gush of water.
