Much of the Middle Temple was destroyed in a fire in 1678, which caused more damage to the Inn than the Great Fire of 1666. The Thames being frozen over, beer from the Temple cellars was used to fight the fire, which was eventually only contained by blowing up some buildings with gunpowder. The Lord Mayor of London tried to exploit the occasion to assert his own jurisdiction over the Temple – which was independent of the City – and on being thwarted in this endeavour, he turned back a fire engine which was on its way to the fire from the City.
