The Saints Peter and Paul Cathedral is a Roman Catholic cathedral in Ulaanbaatar, Mongolia, designed by Serbian architect Predrag Stupar and consecrated in 2003 by Cardinal Crescenzio Sepe; its shape resembles that of a yurt.^[1]

It is the official episcopal see of the Apostolic Prefecture of Ulaanbaatar.

Building

It has 36 semicircular windows and a window in the skylight. They were added by 2005, and were part of a project of Brother Mark,^[2] a member of the Taizé Community. The windows depict the four evangelists in their symbolic forms: an eagle, an angel, a yak and a snow leopard. The latter two are the local reinterpretations of traditional Christian iconography, which replace the traditional winged bull and a winged lion.^[3] Inside is a statue of the Virgin Mary, venerated after being discovered in the rubbish in 2013.^[4]
