Romanesque art refers to medieval art between the 10th and approx. 12th century, i.e, the rise of Gothic art. It originated in Italy inspired by the art of Ancient Rome, and can be seen most often in architecture, decorative art and painting. Romanesque style was spread by the Catholic Church, which at the time was the dominant landowner and thus had the money to build impressive churches. Hence the Romanesque style became the first Pan-European artistic style which expanded throughout the entire Catholic Europe.
