Romanesque.

The Church of Saint Sernin in Toulouse, France is a perfect indicator of the attitude toward God that was held by the people of that time period. Built around 1100, this large church became an important site for pilgrims to stop at and view the precious relics held inside. The architecture was nicknamed the "pilgrimage plan" rather than the traditional one. 
The structure is unique to its time period in that it is much larger than the traditional basilicas of previous times. With noticable vaulted ceilings, the building is very famously in the shape of a cross. This architecture is different than all earlier churches and sets it apart, tying it solely to Romanesque style.
