The Regaleira Chapel is a Roman Catholic Chapel, and stands in front of the palace's main façade. Its architecture is akin to the palace's. The interior of the chapel is richly decorated with frescoes, stained glass windows and lavish stuccoes. The frescoes contain representations of Teresa of Ávila and Saint Anthony, as well as other religious depictions. Meanwhile, the floor itself offers depictions of the armillary sphere of the Portuguese discoveries and the Order of Christ Cross, surrounded by pentagrams. Despite its relatively small size, the chapel has several floors.
