Hi Joar! I love your artwork they are great as always man
On other hand, I think would be nice addings for the historical buildings the Newgrange tomb in Ireland and Gordian III's tomb in Syria. Both were sites of pilgrimage during the antiquity, being the first in use as place for worship the "ancestors" at least until the arrival of Christianity at the V a.C. And the second was visited by Julian during his ill-fated Persian campaing.
Below two links one about Newgrange and the other about the tomb of Gordian III:
