English Gothic architecture Exeter Cathedral is built in this style, as is the crossing of Ely Cathedral, (including the famous octagonal lantern, built between 1322 and 1328 to replace the fallen central tower), three west bays of the choir and the Lady Chapel. In Scotland, Melrose Abbey was a noteworthy example, though much of it is now in ruins. The Perpendicular Gothic period (or simply Perpendicular) is the third historical division of English Gothic architecture, and is so-called because it is characterised by an emphasis on vertical lines. An alternative name, the Rectilinear, was suggested by Edmund Sharpe, and is preferred by some
Elgin Cathedral tower in 1711. Elgin Cathedral is unique in Scotland in having an English style octagonal chapterhouse and French-influenced double aisles along each side of the nave; in England, only Chichester Cathedral has similar aisles. The chapterhouse, which had been attached to the choir through a short vaulted vestry, required substantial modifications and was now provided with a vaulted roof supported by a single pillar (Figs. 13 & 14). The chapterhouse measures high at its apex and from wall to opposite wall; it was substantially rebuilt by Bishop Andrew Stewart (1482–1501), whose coat of arms is placed on the central pillar.
