What’s in it?

The building

  • Experience the creation of the rotunda and find out why its initial purpose is still a mystery 1700 years later.

Church with underfloor heating?

  • There is a widely accepted narrative that the Rotunda was originally constructed as a bath, but is this the case?
  • Find out why the church has a hypocaust that will suffocate the visitors of the building rather than heating the building itself.

The strange room

  • Who builds a room that does not fit with the overall style of the rotunda?
    And where is this room today?

The mystery of the two graves

  • When the archeologists dug around the church, they found many graves, but two of them seemed odd. The deceased were buried only a few inches from the ground level of the church. These graves, together with one coin, pointed to events of death and destruction many centuries ago.

The eye of the angel

  • If you look closely, you will see that the windows at the dome of the church were narrowed down at some point in time, but why?
  • During the conservation of the Rotunda, the scientists noticed that the plaster inside the church, near the dome, was unusually thick. They drilled a hole into it, and an eye of an angel looked at them from below. The angel will recount the tale of the destruction of the church’s second inscription before it was replaced.

Oh! We almost forgot …
