Coastal defense

The historic Fort Santiago built by the Spaniards in the late 16th century continued to be used as such all the way to the 1940s, when it was the headquarters of the Philippine Division of the U.S. Army. Old canons can still be found scattered throughout the fort today, though I don't know if they are relics from the Spanish or American era. This one is trained on Manila Bay, which used to be much nearer the walls before land was reclaimed from the sea. Trees, weeds and moss now surround and grow on the old fortification. I like that.
