While organizing my old photos I came across 2007 pictures from a visit to Castillo de San Marcos, a fort in St. Augustine, Florida. The fortress was built by the Spanish as part of the time they occupied Florida.
The fortress is of the typical “bastion” type. I am not an expert in this era so I relied on wikipedia which had a nice description. Apparently the grades were built so that cannon would be more effective aiming downward as attackers neared the fortress.
Here is a view of one of the cannon pointed out towards the ocean from which attackers may arrive.
This is a view of the fort itself with the courtyard in the middle.
There were many cannons at the fort. The cannons weren’t all from that fort; some were donated from Spain or other museums. This is a four-pounder.
Here is a 16 inch mortar.
Note the fine detailing on these cannon. Very interesting.
