For those who have never been to Danshui, a virtual tour of the Presbyterian Church and the Mackay Clinic is available here:
The many steps leading up to the main hall were (probably still are) pretty forbidding to little kids who could of course choose to stay on the ground level and attend outdoor Sunday School instead.
In the main hall, there is this famous Yamaha organ from 1909, preserved in the church when it was re-built in 1932. Also, the original bell is now on the ground of the kindergarten. In its heyday, tolling of the bell could be heard all the way across the river in Bali. See here for more details.
And the construction history of the two buildings:
Master 洪泉"司" (洪仔泉) worked with Dr Mackay and built the Mackay Clinic in 1879 (洪 later also built the Oxford College and the old Mackay Residence).
The Church was designed by Dr Mackay's son 偕叡廉 and built in 1932 by Master 樹"司", i.e., 黃阿樹, son-in-law of 洪仔泉.
樹司 had also constructed several buildings in Tamkang High School and Tamsui Girls' High, e.g., the 姑娘樓, 八角塔, and 體育館. And the designers of these buildings also included Rev 吳威廉 (William Gauld, a mathematician) and Rev 羅虔益 (Kenneth W. Dowie, an engineer). Many who had worked with the 洪 father- and son-in-law team later became successful builders and contractors themselves.
