The Mausoleum of the National Memorial Place guards St Stephen’s royal coffin, an ornately carved sarcofagus originated from the Roman times. The mausoleum is decorated by frescoes of Vilmos Aba-Novák that tell the stories of the Holy Right and The Holy Crown. On the colorful windows we can see the scenes of St Stephen’s life.

Once in a year, about the Ossarium is opened for a week. It preserves the remains of the corpse found in the territory. The only identified tomb-the remains of Béla III and his wife, Agnes of Antioch was discovered in 1848, during some earthwork. Later their remains were taken to the Matthias Church where an ornated tomb was erected for their memory. The coffins were taken in the crypt of St Stephen Cathedral. On the lower side of the coffins, the imprint of the body of the royal couple can be seen. Their jewels were taken into The National Museum. Nowadays, the human remains’ identification has been in process by a brand new method. The archaeogenetic can give the possibility to examine the royal remains with high accuracy.
