Castillo De San Marcos National Monument is a tourist attraction in Florida.

Castillo De San Marcos National Monument is a magnificent tourist spot with a diverse and marvellous landscape. The monument is a fort which was built by the Spanish people around the seventeenth century.

The fort is special in itself as it built of Coquina, a kind of stone, which is made up of ancient shells that have bonded together over time. The very design and construction of the monument makes it an architectural landmark. The fort had a capacity to house a thousand soldiers and a hundred guns. One of the major attractions in the fort are the cannons that are centuries old and made at different places around the world. Tourists can also visit some of the neighbouring attractions like the Southeast Archaeological Conservancy and Fort Matanaz, if time permits.
