The original design for St Andrew's Church included a short tower but the Town Council opted for a 51m steeple, built in 1787. It contains a unique peal of eight bells cast in 1788 by William and Thomas Mears at the Whitechapel Bell Foundry, the oldest complete ring in Scotland. The bells were refurbished in 2006 and restored to full change ringing. The original Georgian crown glass sash windows with glazing bars no longer exist. Of the replacements the most noteworthy are stained glass windows depicting The Beatitudes by Alfred Webster (1913) and The Son of Man by Douglas Strachan (1934).
