A green iguana peers out of a slot in the wall of the Castillo de San Cristóbal in Old San Juan, Puerto Rico. This fort is the largest ever built by the Spanish in the New World, though part of it was destroyed in 1897 to provide better traffic flow in and out of the walled city. It is now a National Historic Site.
An old house on the outskirts of Ybor City in Tampa, Florida. How or why this building is still standing is a tough question to answer. Someone thinks it is important. A sign on the front porch announces that security cameras are in use.
Fort Zachary Taylor is Florida's southernmost state park. It was built in the mid 1800's as part of a series of forts designed to protect the southern coastline of the United States and played an important part in the US Civil war and the Spanish-American war. Located in the middle of an operating military base, it is undergoing restoration work. In this photo the flag is shown at half mast on the parade ground.
