A magnificent façade outside, and inside elegance just exudes in this beautiful Georgian building right opposite Windsor Castle; a great location and history combined. This is the biggest venue space in Windsor and is the perfect setting for any distinguished business event.
World class facilities include high speed internet access, state of the art audio-visual equipment, and the services of your own dedicated events planner, who will take care of all the details and ensure your event is a resounding success. Whatever your event, there's a room to fit the bill; period features have been lovingly restored to their former glory to bring you refined function space over 11 rooms, for up to 400 delegates.
The bigger rooms are unbeatable for larger conferences, presentations, awards ceremonies and gala dinners, and the smaller rooms are superb for all manner of executive meetings, seminars and training sessions. Combined, the Windsor & Georgian Rooms have a capacity for up to 400 people in theatre style and 300 for a banquet; alone, the Windsor can accommodate 240 delegates at a theatre style conference and 190 for a gala dinner, and the Georgian, 80 and 72 guests in the same layouts. The Balmoral, and the Sandringham Rooms seat 80 people in theatre style and 70-72 for dinner, or 30 in U-shape. For those more discreet board or syndicate meetings, the Blenheim Boardroom and the Chatsworth & Hampton Rooms combined seat 16 executives; the Hampton and Holyrood seat 10, the Chatsworth 8, and the Warwick 6.
Please note that starting November 2025 the hotel is undergoing a £9.5 million refurbishment. During this multi-phase transformation, the hotel will only be able to offer 64 bedrooms as the others are upgraded, and in addition there will be no separate restaurant or bar until June 2026. All meetings and events spaces remain open and fully operational during the transformation which is scheduled for completion towards the end of 2026.
Castle Hotel Windsor has charged parking, and Windsor train station is a short stroll away. London Heathrow Airport is just under 12 miles distant, whilst London City and London Gatwick Airports are both within an hour's reach.
