London’s Ancient Roman Bathhouse Reopens for Guided Tours 2026
A Remarkable Piece of Ancient London Returns to Public View
History enthusiasts in London have reason to celebrate this spring, as one of the capital's most extraordinary archaeological treasures has reopened its doors to the public. The Billingsgate Roman House and Baths, nestled beneath street level on Lower Thames Street in the City of London, is once again welcoming visitors on guided Saturday tours running from April through to November 2026. Dating back to approximately AD 150, this remarkable subterranean site preserves the remains of a private townhouse and its adjoining bathing complex, believed to have belonged to some of the wealthiest residents of Roman Londinium. While modern-day londoners flock to world-famous london attractions like Trafalgar Square for their weekend outings, this hidden gem offers something altogether different — a genuine step back nearly two millennia into the city's earliest chapters. Tickets are priced at £16.96 for adults and £11.55 for children aged 14 and under, as well as concession holders, inclusive of a booking fee. It is a modest price for what amounts to one of the most immersive historical experiences available anywhere in the capital, and bookings are already open for those eager to secure their place.
Inside the Ruins: What Visitors Can Expect to See
Stepping into the Billingsgate Roman House and Baths is unlike any typical london events experience on offer in the city. The guided tour takes visitors through the excavated remains of a sophisticated bathing suite that once served the Roman elite of Londinium. Much like the grand public bathhouses of ancient Rome itself, this private complex featured distinct rooms designed for different temperatures. Visitors can view the frigidarium, or cold room, the tepidarium, a warm intermediate space, and the caldarium, the hottest chamber of all. Historians note that the tepidarium experience in Roman times occasionally involved rather uncomfortable hair-removal rituals — a detail that tends to capture visitors' imaginations. The site was first uncovered in 1848 when construction workers excavating foundations for the Coal Exchange on Lower Thames Street stumbled upon the ruins quite by accident. The discovery was celebrated at the time by the Illustrated London News as a find of enormous significance for those interested in London's ancient past. Today, an office building sits directly above the site, making the contrast between contemporary city life and these ancient remains all the more striking and atmospheric for those who venture below.
Why This Discovery Matters to the Local Community
For residents and communities across Greater London, sites like the Billingsgate Roman House and Baths serve as a powerful reminder of just how layered and rich the city's history truly is. Long before the landmark london attractions that define the skyline today, Londinium was already a thriving urban settlement, home to merchants, officials, and families living sophisticated lives. The reopening of this site contributes meaningfully to the local cultural calendar, offering schools, families, and history lovers an accessible and affordable way to connect with that legacy. It also sits within a broader context of exciting Roman discoveries in the area — in early 2022, two exceptionally well-preserved Roman mosaics were unearthed near London Bridge, believed to be part of an ancient upmarket inn that once served travellers crossing the Thames. Those interested in exploring London's Roman heritage can look forward to a season of saturday tours running through november 2026. The site is also worth distinguishing from the so-called Roman Bath near Temple on Surrey Street, which despite its name has no genuine Roman origins. For authentic history right beneath the city streets, Billingsgate remains unmatched and is a genuinely unmissable addition to any londoner's cultural bucket list.
