The answer is in Duncan Steel's book "Marking Time"

The answer is yes, and it is evident in the orientation of churches
in England built before and after the English calendar reform in 1752.

Churches were built oriented to sunrise on their saint's day.
In 1752 the calendar shifted, and sunrise shifted.  Additions made to
pre-reform churches were oriented to sunrise on the new saint's day.
The result was "crooked churches".  Steel counts 81 such churches
within Oxfordshire alone.
