Several characteristics separate the Romanesque and Gothic style. The Romanesque style takes elements from Roman architecture. Romanesque structures sometimes incorporate Corinthian capitals on the columns and, in most cases, have semi-circular arches. The buildings have thick walls and buttresses attached to the walls. This comes in contrast with the Gothic style. Gothic structures often have pointed or ogival arches, which makes the structure seem more elongated. The columns are often clustered columns that stretch out in many directions. There are more flying buttresses, which are buttresses that are detached from the walls. Additionally, the Gothic style is more decorated and ornamented compared to the Romanesque style.
