Located on the opposite side of Warriston Road from Warriston Cemetery, in NE Edinburgh, Warriston Crematorium was built in 1808 as East Warriston House for Andrew Bonar, an Edinburgh banker. In 1929, this two-storey villa was converted to its present use by the architectural practice of Lorimer and Matthew, making it the second oldest crematorium in Scotland. The internal walls of the original building were removed to create a white-painted vaulted chapel, lit by tall arched windows on the south side. This is now known as the Lorimer Chapel and seats 230 people. There is a fine arched tripartite stained-glass window in the apse. A second chapel, the Cloister Chapel seating 60, was added in 1958. The Lorimer Chapel was remodelled in 1967. Warriston performed 1787 cremations in 2011.
Warriston is owned by Edinburgh Crematorium Ltd., a private company founded in 1928 by the Edinburgh Cremation Society, in order to provide cremation facilities for the people of Edinburgh. In 1965, this company also acquired the Seafield Cemetery and Crematorium, located 2 miles (3 km) to the east. Warriston is now Scotland's second-busiest crematorium, with 2234 cremations in 2017.
