Second Tower (Cesta / Fratta)
Highlight • Castle
Towards the end of the 16th century, having lost its strategic importance, the Tower fell into disuse until 1930 when, as part of the modernization of the country resulting from the construction of the Rimini-San Marino railway, it was decided to restore the medieval monuments to encourage the influx of tourists to the Titan.
Today it houses the Museum of Ancient Weapons, which includes about 535 objects including sidearms, auction weapons, firearms, bows, crossbows, and armor all dating from various periods between the Middle Ages and the end of the 19th century.
Tickets: 6.00 euro cumulative with the First Tower
Opening hours: Sept 6 to June 06: 9 a.m. – 5 p.m, from June 07 to Sept 5: 9:30 a.m. – 6.30 p.m.
