The pointed arches and ribbed vaults at the back end of the church are typical gothic features.
An interesting feature of this church is the wooden barrel-vaulted ceiling over the nave. I've seen this same style of construction in a few other churches in our area, right down to the painted tie beams that span the space. I think this ceiling may be a vestige of the romanesque style as it transitioned into the gothic period. When this church was constructed, between the 12th and 13th centuries, the transition was in full swing. The stone work from the transept into the choir is very obviously gothic (pointed arches and ribbed vaults, for example), but there's nothing gothic about the barrel vault.
