A rare Roman fort and marching camp have been discovered in Wales by aerial archaeologists during the hot summer.
The major Roman fort complex was spotted on parched grassland near Brecon, Powys, and the marching camp near Caerwent in Monmouthshire.
Aerial archaeologist Toby Driver said he could not believe his eyes when he spotted the fort from the air.
Scores of Iron Age farms and forts were also found in Pembrokeshire and the Vale of Glamorgan.
Mr Driver spoke to Peter Johnson on BBC Radio Wales.
