The "New Market House" was used as Toronto City Hall from 1845-1899. The yellow brick outline of the center part of that building can still be seen today in the front facade of the current building. The City Hall was renovated in 1851 by William Thomas, with new shops in the wings, keystones in the arched windows and improvements to the police station and jail cells (which were reportedly subject to flooding). More improvements were made between 1868 and 1872 by Henry Langley, who designed many churches and public buildings including the Metropolitan United Church. Railway lines were located on infill as the shoreline moved further south of the building.
