About

Calculus Lodge No. 3575 is a masonic Lodge that meets on Saturdays in Central London. We are a group of like minded men over the age of 18 that welcome newcomers or masons looking for an additional Lodge.

As well as our workings and masonic advancement we offer a strong social calendar for both members and their families. We also carry out a large amount of fund raising and take part in local activities.
