Castillo De San Marcos Hiking Medallion

The shape of Castillo de San Marcos, the oldest masonry fortress in North America, provided a stout defense for colonial Spanish St. Augustine. The main walls, which are lined with bombproof vaults for storing food and ammunition, form a large hollow square. At each corner large, diamond shaped blocks called bastions project out. Sentries on the bastions could watch all the surfaces of the forts walls with no hidden blind spots. Commemorate your trip to this amazing park with this Castillo De San Marcos Hiking Medallion!
