Carroll William Westfall has claimed that building types can serve as natural symbols of (the purposes served by) activities such as venerating, celebrating, trading, and dwelling. The aim of this paper is to interpret Westfall’s claim in a way that makes it non-trivial and yet worthy of further investigation. In particular, an attempt is made to explain the connection between building types and what they symbolize without appealing to convention. The question is also answered whether a non-conventional connection is compatible (...) with one and the same building type having a different significance in different cultures. (shrink)
