Public Lectures

From September to March the Society organises a programme of public lectures on cultural, scientific and antiquarian subjects. These have been held almost continuously since 1889 and are considered one of the most important aspects of the Society’s work.

The lectures are held on Friday evenings commencing 7.30 p.m. The lectures running through the autumn of 2021 will be held at Spalding Methodist Church in Broad Street, directly opposite our museum. Admission will be £3.00 per person. We ask that only people who are fully vaccinated or have passed a recent clear Covid test should attend in person. We plan to live stream the lectures for the benefit of those unwilling or unable to attend at the venue. Booking will required to access the stream at the same cost, £3.00.
