In Rambles Around Kilmarnock (1875) Archibald R Adamson described it as "most spacious, although of a most peculiar form, having no less than seven streets branching off it.
In the centre stands a marble statue of Sir James Shaw, who rose from a humble position to that of Lord Mayor of London",[1] the square is part of the area nicknamed "the town" by locals.
[3] In order to try and control traffic flow around the area, several methods were used, including a roundabout at one point.
In 1924 the bus station was established in Portland Street, this continued to serve the town until it was closed and later demolished in the 1970s.
Portland Street has been completely demolished and rebuilt with new modern buildings which have become shops, a bingo hall and a super pub.
