style with solid masonry, large round piers, round arches and smallish round headed windows. These features may still be seen in the south transept and the remaining two bays of the nave, which are now used as the Chapel of the Border Regiment. The stone is the local red sandstone, which has discoloured almost to black on parts of the exterior. The building has also suffered from subsidence which is evidenced by the piers, which lean at different angles. In the 13th century, the choir of the cathedral was rebuilt in the Gothic style, wider than the original and on a different axis. However, the new work was severely damaged in a fire in 1292, and the work was recommenced. By 1322 the arcades and the easternmost bay were complete, with the elaborate tracery and glass of the east window being in place by about 1350. The upper stages of the walls were finished, probably by the architect John Lewen who died in about 1398. The Gothic arcade has richly moulded arches with dog-tooth decoration, and the twelve capitals are carved with vegetation along with small lively figures representing the labours of the months. The choir is roofed by a fine wooden barrel vault dating from the 14th century. In 1856 this was restored and repainted to a new design by Owen Jones. It is thought the eastern bays of the cathedral never received a stone vault because at some point the central spire blew down, and funds were required to rebuild the damaged tower and north transept, completed in about 1420. The most significant architectural feature of Carlisle Cathedral is its East Window. The tracery of this window is in the most complex of English Gothic styles, Flowing Decorated Gothic. It is the largest and most complex such window in England, being 51 feet high and 26 feet wide. It has nine lights, and tracery, which, it has been calculated, was drafted from 263 points. The tracery of the window still contains much of its original medieval glass. Carlisle Cathedral has a fine set of 46 carved wooden choir stalls with misericords, which were installed in the early 15th century. Misericords are hinged seats, "constructed to keep the monks from falling asleep while at prayers," and carved with numerous figures and creatures. Despite their purpose, the "pillars supporting the canopies bear traces of having been burnt, by weary monks
