The tall spire of timber, covered with lead, which originally crowned this tower reached an altitude, it is said, of 525 feet; but this is doubtful. This spire was blown down during a tempest in January 1547-8.
Between 1307 and 1311 the central tower was raised to its present height. Then around 1370 to 1400 the western towers were heightened. All three towers had spires until 1548 when the central tower's spire blew down.
