Emulation Lodge of Improvement is a Lodge of Instruction which first met on 2 October 1823, and is held under the sanction of Lodge of Unions No. 256 in the English Constitution. It restricts admission to Master Masons in good standing. The aim of the lodge is to preserve Masonic ritual as closely as is possible to that which was formally accepted by the newly formed United Grand Lodge of England in 1816 and as amended since.
