Host with purpose
The Royal Maritime Hotel is Portsmouth's largest dedicated conference venue. Booking your conference, meeting or training day with us means more than a good day's work — a portion of the revenue from every event is reinvested into our charitable foundation, supporting serving and veteran armed forces personnel and their families.
It's the ethical choice for your business gathering — and just a five-minute walk from Portsmouth Harbour station, Gunwharf Quays and the Historic Dockyard.
