St. Capitolina Abbey

 is the Prontera monastery where budding Acolytes go to become Monks. It features a secondary graveyard for the citizens of Prontera.

Story
Many years ago, a group of heroes rose up to oppose the great demon Baphomet. They sacrificed their lives to seal the demon away and bring peace to Midgard. A shrine was erected over Baphomet's grave, which eventually grew into a full abbey. However, Baphomet's power continued to grow and the magical seal that imprisoned him grew weaker as time went by. When Surt broke free of his prison underneath Morocc, the monks grew worried that Baphomet will soon break from his seal as well.

Ragnarok Online II
The land that the abbey is built on sank beneath the sea during the Day of Despair. Therefore, it no longer exists by RO2's time. Acolytes wishing to become Monks must now do so at the new cathedral in Prontera.
