The Masonic Hall in Taunton, Somerset, is designated by Historic England as a Grade II* listed building.

Opened in 1822, St George's Chapel served Taunton's growing Catholic community for over 35 years, before they moved to a larger church which was completed in 1860.

After being rented out for a time, when it was known as St George's Hall, the building was then sold in 1878 to a company acting on behalf of a group of Freemasons, who purchased it to provide a home for the Unanimity & Sincerity Lodge.

[3] Within 35 years, the congregation had swelled, and St George's Chapel was no longer large enough to serve the Catholics of Taunton.

The nearby Franciscan Convent purchased a plot of land adjacent to their own in 1858, and St George's Church was opened in April 1860, to replace the chapel of the same dedication.

The Unanimity & Sincerity Lodge had originally met in Ilminster after their constitution in 1788, and moved to Taunton in 1797, meeting at the London Inn.

It has a stucco front, with two pairs of Ionic pilasters; the larger ones frame the building, and appear to support an overhanging cornice with a decorative dentil finish.
