Overview
The Three Mariners Inn is a pub and bar in Tenby, Pembrokeshire, Wales, trading as Three Mariners Tenby. It occupies a Grade II listed building on the south-west corner of the junction with St Mary's Street, placing it in the historic heart of the seaside town. The pub presents itself as a friendly local with a broad offer: freshly prepared food, a well-stocked bar, and an entertainment programme built around karaoke, live music and DJs, with late-night dancing until 1am. Its website invites visitors to book a table by sending preferred dates and party details for confirmation, and highlights the kitchen, the bar and the DJs as its main draws. The business is a single-site hospitality venue rather than a multi-outlet chain, and no parent company, founding date or ownership details are established in the available evidence. Its significance in the brand knowledge base is as a named, website-trading pub brand in a UK tourist town, combining a listed historic building with a contemporary food-and-entertainment proposition aimed at both residents and visitors.
History
The Three Mariners Inn is documented as a Grade II listed building in Pembrokeshire, situated on the south-west corner of the junction with St Mary's Street in Tenby. The listed status indicates the building is of special architectural or historic interest and is protected under UK heritage legislation, though the available evidence does not give a construction date or a listing date. As a trading pub, the business operates under the name Three Mariners Tenby and maintains a website at threemarinersinn.com. Its current proposition, as described on that site, centres on freshly prepared food, a well-stocked bar, and an entertainment schedule of karaoke, live music and DJs, with dancing continuing until 1am. The pub accepts table bookings via a form requesting preferred dates and party details. No founding year, founder, ownership chain, or corporate parent is established in the supplied evidence, so the venue is best treated as an independent single-site hospitality brand. Its history in the brand sense is therefore primarily the story of a named historic building repurposed and marketed as a modern food-and-entertainment pub in a popular Welsh coastal resort.
