In the centre of the western side of the forum of Astorga, a room or chamber was built , preceded by an entry with columns and ended in an apse. This arrangement and the sumptuous paving of marble sheets (optus sectille) creating geometric by-chromatic motifs have led to identify it with a temple dedicated to the memory of Emperor Augustus, to promote the imperial cult.
The Aedes is made in opus caementicium or Roman concrete, and would reserve the apse-shaped ornamental top to a missing altar dedicated to the imperial cult, where the augur would carry out sacrifices of small animals, probably birds.
