Motte-and-bailey castle
The Motte-and-bailey castle of Moutte was fortified for the first time in the second half of the 9th century: built on a platform of 450 to 500 Sq. M, two residential buildings were constructed: one using the ancient technique of "murus gallicus". This building of 30 Sq. M is surrounded by a gallery on two sides, the other building is about 50 Sq. M. The two were deliberately burned shortly before the year 1000, to backfill the mound again to raise it by about 2 metres. The second construction consisted of a single building of 54 Sq. M, which caught fire in 1010 during an attack. It is possible that the construction of Castellet castle corresponds to the destruction of the first castle.
