Bath Tower Travel Guide

Bath Tower stands as one of Caernarfon's most extraordinary places to stay—a genuine 13th-century bastion tower integrated into the town walls of the legendary castle. Built as a defensive half-tower with walls of rough-hewn sandstone up to several feet thick, it has witnessed nearly 800 years of Welsh history. The tower's thick walls, shaped by medieval craftsmen, still bear the marks of centuries of footsteps smoothed into the ancient stone. What makes this structure particularly special is its transformation from fortress to Victorian leisure destination and finally to a cherished holiday home that preserves its historical character while providing modern amenities.

During the 19th century, Bath Tower underwent a remarkable reinvention. It became part of an ambitious Victorian bathing establishment, complete with hot, cold, and shower baths supplied by seawater pumped from the sea. The facility was described as "replete with every accommodation," featuring a news room, museum, billiard room, and concert hall—reflecting the leisure aspirations of the Edwardian era. The stained-glass windows that now cast purple light across the kitchen and bathroom date from around the 1850s, when a college acquired the tower and adapted it for their own use, even converting the upper floor into a chapel. These Victorian touches remain visible today, adding layers of character to the medieval structure.

The tower's interior unfolds across multiple levels connected by a narrow spiral staircase, each floor revealing distinct rooms with their own character. The ground floor features a large dormitory-style room—originally the dungeon—where visitors can sleep like soldiers of the garrison, with slate flooring laid during 20th-century renovations. The first floor contains a spacious bedroom with enormous windows flooding the space with natural light, ideal for families with children. The second floor houses the main living area, a generous sitting room dominated by a wood-burning stove and high ceilings that create a grand yet intimate atmosphere. A small but well-equipped kitchen and bathroom occupy this level, both graced with those distinctive purple-tinted stained-glass windows. The master bedroom on the third floor opens onto a turret balcony—a magical vantage point for watching sunsets over the town and sea, or simply observing daily life in Caernarfon below.

The tower has been carefully restored to balance historical authenticity with contemporary comfort. Major conservation work in 1967 established the current layout, while subsequent improvements in 1997 added a wood-burning stove and limewashed the bare stone walls, creating a warmer and lighter interior. In 2008, the roof was re-lined to address water seepage, and external stonework was re-pointed in 2010 to preserve the building for future generations. These interventions respect the tower's medieval origins while ensuring it functions as a comfortable modern holiday home. The result is a space where history is tangible—in the thick walls, the spiral stairs, the medieval proportions—yet entirely livable.

Bath Tower's position within Caernarfon's town walls is integral to its appeal. Access is gained either through a narrow alley from the street behind or directly from the sea wall itself, adding to the sense of discovery and separation from the modern town. The tower's survival is remarkable; Caernarfon's relative poverty in the 17th and 18th centuries meant the town did not expand through or over the walls, preserving them intact. The encircling wall-walk and the remarkable survival of two main twin-towered gateways and eight bastions create an authentic medieval townscape that few places in Britain can match.

Staying at Bath Tower is fundamentally different from conventional holiday lets. Guests describe the experience as stepping into the past while enjoying modern conveniences—a quality that transforms a weekend away into something that feels far longer and more restorative. The tower's generous proportions, despite its medieval origins, provide ample space for groups and families. The thick walls provide excellent sound insulation, while the multiple levels and distinct rooms allow for privacy and separation. Whether curled up by the wood-burning stove with a book, standing on the turret balcony watching the light change over the landscape, or exploring the town's narrow streets just minutes away, Bath Tower offers a uniquely immersive connection to Welsh history and medieval architecture.
