The monastery was built far away from the rest of the Spanish colony on the island, located far upriver in the mountains. As with all structures on the island, it fell into ruin after the Spaniards fell victim to El Dorado's curse.
It consists of several buildings and courtyards, most notable a library and a large church. The library contains a secret room that leads to a series of catacombs which run underneath the entire area. They also lead into the church, which itself contains a hidden "gallery" that shows the entrance to the El Dorado treasure vault. Behind the church is a graveyard, which contains a mausoleum, which itself contains the hidden entrance to the treasure vault.
Beneath the monastery
Many of the monastery's structures lie below ground. The treasure vault is located in a large cavern beneath the graveyard. A network of hidden, interlinked catacombs also run underneath the church and library. The German submarine bunker was also constructed under the monastery, a short distance from the church. As a result, all of the above locations are in extremely close proximity, often overlapping. For example, the treasure vault contains an entrance to the German bunker.
