Wilton's is a unique building comprising a mid-19th Century grand music hall attached to an 18th-century terrace of three houses and a pub. Originally an alehouse dating from 1743 or earlier, it may well have served the Scandinavian sea captains and wealthy merchants who lived in neighbouring Wellclose Square. From c. 1826, it was also known as The Mahogany Bar, reputedly because the landlord was the first to install a mahogany bar and fittings in his pub. In 1839 a concert room was built behind the pub and in 1843 it was licensed for a short time as The Albion Saloon, a saloon theatre, legally permitted to put on full-length plays. John Wilton bought the business in c. 1850, enlarged the concert room three years later, and replaced it with his 'Magnificent New Music Hall' in 1859.
