Rood arches are architectural elements that have been used in religious buildings for centuries. They are also known as triumphal arches, chancel arches or crossing arches. These arches were originally designed to support the rood screen, a barrier that separated the chancel from the nave in churches. Rood arches became a popular feature of Gothic architecture during the 12th century, and were often richly decorated with carvings and sculptures. Other synonyms for rood arches include choir arches, sanctuary arches, nave arches, and transept arches. Despite their various names, all of these arches share the same function of separating the sanctuary from the remainder of the church.
