Behind the TSB

Where is this?

Why the Monogram Here?

A Google serach revealed the following information:

The Identity Behind the Letters

While the front of the structure at 6 Market Place was historically tied to the Lordan family's Stamp Office, the architectural expansion and remodeling at the rear of the bank block were executed by the Wilts & Dorset Bank. 

• The Monogram Letters: The carving intertwines the "W" (the central vertical anchoring line and its lower pronged curves), the "D" (the prominent right-hand loop), and the "B" or "C" (the left-hand and outer framework curves). Together, they form a stylized corporate crest for the Wilts & Dorset Banking Company.

• The Merging of Premises: Built originally around 1800, the neighboring premises initially housed William Footner’s Bank before being acquired by the Wilts & Dorset Bank. As these regional banks grew in the late 19th and early 20th centuries, they heavily renovated, expanded, and merged structural plots to accommodate larger secure vaults and staff offices—often leaving corporate stonework on the newer brick extensions at the rear.

• Corporate Takeovers: In 1914, the Wilts & Dorset Bank was officially taken over by the Lloyds-affiliated Capital & Counties Bank. Capital & Counties subsequently consolidated their operations by moving their staff into the No. 6 Market Place premises (which eventually became the modern TSB branch). 

Leaving a monogram on a building extension was a common practice for Victorian and Edwardian banks to project permanence, wealth, and institutional pride into the local community.
