This part of the Girona History Museum was on the basement floor of the former Capuchin brothers’ monastery of Sant Antoni, and is the oldest part, dating from before 1762. Among the parts of this floor we might note the cistern, an interesting example of a water tank with stone vaults set on pillars, measuring 15 metres high and 10 x 10 metres wide, used to collect and store the rainwater to supply the monastery.
