It is situated on a hill between the rivers Trebižat and Neretva, 5 km south of Čapljina, alongside the road to Gabela in Bosnia and Herzegovina.

An Italic settler had a private manor complex built for agricultural purposes on the Mogorjelo site in the mid first century CE.

[1] In the early fourth century, a state-owned estate was constructed over the ruins, with a villa which now forms the major feature of the complex.

[1] The latest coins discovered on this site, in a layer of soot, were minted by Honorius in 388, so that it may be assumed that Mogorjelo fell into enemy hands some time between 401 and 403 with the Visigoth invasion of these parts.

In the mid fifth century, two basilicas were erected within the ruined perimeter walls in the north-eastern corner of the former villa, first one to the north and immediately thereafter the one to the south.
