Victorian coal exchange transformed into luxury hotel and event venue in Cardiff Bay's historic Mount Stuart Square.
The Coal Exchange Hotel occupies a magnificent Grade II* listed Victorian building in Cardiff Bay's Mount Stuart Square, originally serving as the world's first million-pound coal deal location. This historic venue combines original period features with contemporary luxury, offering elegant event spaces and boutique accommodation. The building features stunning original architecture including ornate ceiling work and period windows, making it ideal for weddings, corporate events, and conferences. Located in the heart of Cardiff Bay's cultural quarter, guests enjoy easy access to the waterfront, Millennium Centre, and city center attractions.
This venue will soon include AI-enhanced arrival information, travel insights and attendee feedback via Smart Event Journeys™, powered by Jigsaw Conferences.
