The big Balearics building society, Sa Nostra, has a cultural foundation in Can Castelló, where it stages exhibitions. It is worth popping by just to check out the fine 18th-century courtyard, which now hosts a hip cafe. The temporary exhibitions at the centre are always worth a look.

The original house dates to the previous century, and it even has a few Modernista touches from renovation work done in 1909. Just in front of it is Font del Sepulcre, a Gothic baptismal font left over from a long-disappeared church. Inside it is a 12th-century Muslim-era well. Carrer de la Concepció used to be known as Carrer de la Monederia, as the Kingdom of Mallorca's mint was on this street.
