Martyrium.

Martyrium.

The name of a church built over the grave of a martyr, or called by his name to preserve the memory of him, had usually the distinguishing title of martyriunm, or memoria martyrum. Instances of this kind of designation occur with great frequency in the writings of Eusebius, Augustine, etc. Eusebius calls the church which was built by Constantine on Calvary, in memory of Christ's passion and resurrection, Martyrium Salvatoris.
