Prior to 1920, when Leith and Edinburgh merged, it was necessary to use both entrance doors because Leith and Edinburgh magistrates set different licensing rules. The main effect of this was that the bar on the Leith side served until 9.30pm and after that the customers could adjourn to the Edinburgh side to enjoy additional drinking time. Pilrig Church (now Pilrig St Paul's Church) is visible along the entire length of Leith Walk. It was designed by architects Peddie and Kinnear and constructed (1861–63) originally for the Free Church of Scotland. It has a fine interior, including early examples of stained glass by Daniel Cottier and a historic organ by Forster and Andrews (1903). The hall to the rear blends in perfectly but is a later addition from 1892 On the upper Elm Row section, midway between Brunswick Street and Montgomery Street, are the remains of what was built as William Williams' New Veterinary College. Only the front building remains, as the complex of stables and support buildings were demolished to create student housing in 2014. The front building was designed in 1872 by William Hamilton Beattie with sculpture by John Rhind. The sculpture was removed and ornate ground floor lost in the 1970s when converted into studio space for Scottish Television's Gateway Studios. The main college structure stood to the rear and contained a fascinating combination ranging from stained glass to stables. The huge rear college complex was demolished in 2014 to make room for student housing. Other recent losses include the "Craig and Rose" paint and varnish works at Steads Place and Springfield Street, famous suppliers of the red paint used on the Forth Bridge (which was used as their company logo). This site has been redeveloped as housing. Leith Walk terminates (in colloquial terms at least) at the Omni Centre and St. James Centre at its southern end. The lower northern end terminates where Great Junction and Duke streets meet. Trams Leith Walk was one of the first and last places in Edinburgh and Leith to see trams. Leith had Scotland's first electric tram in 1905. On Leith Walk this terminated at Pilrig Church and passengers had to change to Edinburgh's cable-drawn cars. This messy changeover was known as the "Pilrig muddle". Edinburgh did not electrify its system and smooth out this problem until 1925. Edinburgh's "last tram" of the earlier tram era ran in 1956 and
