London’s grandest town palace was funded by a systematic, scandalous scheme of religious persecution.

In short: The Mansion House is a masterpiece of Georgian architecture and the official residence of the Lord Mayor of London. Yet, its construction was financed through a cynical legal trap that extorted thousands of pounds from wealthy religious dissenters who were systematically targeted for their refusal to take Anglican sacraments.

Designed by George Dance the Elder and completed in 1752, the Mansion House stands as a Grade I listed monument in the heart of London. While its Palladian design and the magnificent Egyptian Hall—inspired by Roman interpretations of Egyptian columns—are celebrated today, the building’s origins are rooted in a period of intense institutional discrimination. In the 18th century, the City of London Corporation required officials to take Anglican communion, a practice that violated the conscience of many non-conformist Christians.

To fund the construction, the City authorities devised a predatory system. They intentionally elected wealthy Dissenters to the office of Sheriff, knowing full well these individuals could not serve due to their religious beliefs. When the candidates inevitably refused the post, the City levied heavy fines against them. This practice, described by historian William Edward Hartpole Lecky as a scandalous form of persecution, successfully extorted at least £15,000. The scheme was so aggressive that the City even targeted individuals who were blind or bedridden, purely to extract their wealth.

The abuse of power persisted for decades until a man named Evans launched a legal challenge that lasted ten years. In 1767, the House of Lords finally intervened, ruling against the City’s practices by drawing on the Toleration Act of 1688. Today, the Mansion House serves as a hub for hospitality and business, housing the prestigious Harold Samuel Art Collection. While it remains a symbol of the City’s financial power, it also stands as a historical monument to the unjust treatment of Dissenters during the 18th century.
