third white cloth hall. Thanks to some sensitive restoration you can still see the front of this building (right, now occupied by Pizza Express). It was planned by wealthy Leeds merchants - spurred on by the opening of a rival cloth hall at Gomersal - and built on the Tenter Ground in the Calls. As the name suggests, the white cloth hall sold undyed cloth, whereas the mixed or coloured cloth-makers used the market in Briggate. It was constructed around a large central courtyard and it was two storeys high at the northern end (as mentioned, The Assembly Rooms were on the second floor). Big public events were sometimes staged in the courtyard, such as Mr Lunardi's balloon ascent in 1786.
second white cloth hall, and was installed in 1786, when that building was demolished. The third white cloth hall was restored in 1991, and it was at this time that a small bell was put into the cupola (it's struck by an internal electric clock hammer, though rarely sounds now).
With the coming of the railway in 1865, they actually had to build a fourth white cloth hall (though the North Eastern Railway company did foot the bill for it). You can see in my photograph below how the North Eastern Viaduct literally sliced the New Assembly Rooms in half. Ironically this fourth hall was never fully used, and was demolished in 1895, though the building that now stands in its place (a hotel) also sports the original cupola, carefully preserved for posterity.
