A 360° View of Castillo de San Cristóbal\'s Interior
A 360° view of the interior of Castillo de San Cristóbal. One can see concrete blocks scattered on the lawn (left by the U.S. army in 1960), and the high embrasures of the second tier. A ramp leads up to said tier on the right, a large casemate on the left was likely used to hold supplies during Spanish occupation of the fortress.
