In architecture, "Romano-Gothic" is a term for an architectural style, part of Early Gothic architecture, which evolved in Europe in the 12th century CE from the Romanesque style, and was an early style in Gothic architecture. In England, the style is usually termed "Transitional". The style is characterized by mixing rounded and pointed arches. Flying buttresses were used, but are mainly undecorated. Romanesque buttresses were also used. Romano-Gothic began to use the decorative elements of Gothic architecture, but not the constructional principles of more fully Gothic buildings. However, walls did start to become thinner through the use of pointed arches and ribbed vaults to distribute weight more evenly.
