Fort Santiago is a ruined old Spanish fort, now used as a park. A collection of rusting cars which belonged to previous Presidents dot the park. The climb to the top of Fort Santiago is worth the view of the Pasig River. During World War II, the Japanese used the fort as a prison. The dungeons are below the high-tide level and sometimes prisoners drowned here. Right at the end of the war the Japanese started on a wholesale massacre of prisoners, and in one small cell the bodies of 600 people were later found. The Rizal Shrine Museum is probably the most interesting part of the fort. It is filled with items that were used or made by the Filipino martyr, José Rizal, including a farewell poem he wrote on the eve of his execution. The rooms where he was held before his execution can be visited.
