The Anglican cathedral of KL, designed by colonial architect A. C. Norman and consecrated in 1894. It is a modest brick-and-stone Early English Gothic Revival building — a small piece of English parish church transplanted to a tropical city — and its low slate roof and pointed spire stand out among the surrounding modern offices on the north side of Merdeka Square.
The interior is open to visitors during the day. Note the original Henry Willis pipe organ from 1895, still in use, and the brass plaques inside the nave commemorating members of the colonial administration. Services in English, Mandarin, and Tamil. Not a major sight, but a good five-minute stop while walking the colonial core.
