In Rocca Imperiale Marina there is also the 'magazzino', which was built in the 18th century (1731) by order of Duke Fabio Crivelli. It served not only as a warehouse but also as a market, but is not freely accessible nowadays. The art of the craft can also be recognized by the partly collapsed, complex roof structure (entablature). In the immediate vicinity there is an impressive square watchtower from the 16th century. The two buildings demonstrate the importance of Rocca Imperiale in the field of trade and as a strategic location.
This castle, which began construction in 1225, was commissioned by Frederick II of Swabia. The function was that of surveillance of the Gulf of Taranto. Today the castle can be visited every day from 9.30 to 12.30, and from 16.30 to 20.00.
