Princes House History

The architect Thomas Edwards of Greenwich was much in demand, designing fine houses for the Cornish gentry. He built our historic town house in 1739 for Cornish mining magnate William Lemon.

When built, Princes House was the finest in Truro with amazing views of the river. It had stables and both an inner and an outer garden that ran right down to the Quays. Princes House saw some “fine entertaining” as William Lemon was twice the Mayor of Truro and Sheriff of Cornwall. After his death in 1760, Princes House became a family home to his widow and grandchildren.

Just across the road on Quay Street is the Old Mansion House, built by mining giant Samuel Enys in 1707. As Truro became wealthier, more mansion houses were built in this area. Thomas Daniell, previously his agent, bought up Lemon’s mining and merchant businesses. He employed Edwards to design and create “an equally imposing house in the same street” (Colvin). The nearby Mansion House took 7 years to build and reportedly used French slaves as labourers.

At the time of Poldark  (based between 1783 and 1790) Truro was a centre for the fashionable, wealthy and influential people, with Princes Street the place where they lived. Thomas Daniell, in the Mansion House, had become known as ‘Guinea-a-minute’ Daniell and his son, Ralph, was said to be the richest man in Cornwall.

William Lemon’s grandson, Sir William Lemon, was a philanthropist who became Member of Parliament for Cornwall and a Baronet from 1774. He built Lemon Street and developed the bustling Lemon Quay. Lemon Street was completed in the 1830s and ‘the pride of Truro’ became the new residence for the Lemon family and members of the growing business community. At about the same time, Thomas Daniell’s grandson had spent the family fortune and was forced to leave the country to flee his creditors.

Today Princes Street is no longer a residential area but part of Truro’s Artisan District. Princes House is home to a creative community of artisans and small, independent designer businesses. The décor has been preserved and Princes House remains one of the most beautiful houses in Truro, renowned for its pillars, sweeping staircase and decorative plasterwork.
