Interlaced arch

Interlaced arches is a scheme of decoration employed in Romanesque and Gothic architecture, where arches spring from alternate piers, interlacing or intersecting one another.

An example of the former exists in St Peter-in-the-East in Oxford and of the latter in St. Joseph’s chapel in Glastonbury, and in the Bristol Cathedral.

[3] The interlaced arches are most likely an invention of Islamic architecture (cf.

Bab al-Mardum Mosque, 999-1000 AD and Mosque–Cathedral of Córdoba, 833-988[4]).

This decoration was especially popular in England, with the most famous example at Lincoln Cathedral (St Hugh's choir).
