Between the 11th and 13th centuries, Romanesque art developed with a style similar to Roman art. Romanesque architecture featured stone churches built in a Latin cross floor plan with barrel vaults and buttresses. Interior walls, columns, and windows were decorated with paintings on plaster showing biblical scenes to educate the largely illiterate population. Sculptures carved into architectural elements like capitals and altars depicted religious figures and were often colored. Romanesque art focused on religion through the architecture and decoration of churches and monasteries.
