聖胡安堡壘-聖卡塔利納宮

聖胡安堡壘是由一支西班牙軍事工程隊於1589年修築完成的。中美洲群島聖胡安最早被西班牙在1521年佔領，並在海灣入口處的一個小島上建城堡，是西班牙在美洲的一個重要基地。

San Juan was once a Spanish dependency, and since it was an important economic and strategic position in the Caribbean throat, Puerto Rico was bought by the United States. These two fortresses have now become popular tourist attractions.

It's a very historic fortress. It's dark and beautiful facing the sea.

There are many places worth remembering and discovering in the old city of San Juan. The cobblestone trail extends between many old Spanish-style buildings. The fortress built by the Spaniards supported him against many attacks by British and French fleets, making it the earliest settlement in the United States. Nowadays, the old wall of the military base can also see some bullet marks, pits and holes, as if people were back to the era of ice and fire.

La Fortaleza-Palacio de Santa Catalina is a building near the old city wall of San Juan. The main tone is white, very small and fresh.
