Westminster Abbey is primarily closed to tourists on Sundays and during significant religious holidays, as it remains an active place of daily worship. On Sundays, the Abbey is open exclusively for those attending scheduled church services, which are free and open to all, though sightseeing is not permitted during these times. Additionally, the Abbey may close or have restricted hours on short notice for special royal events, state funerals, or national celebrations. For instance, it traditionally closes to the public on Good Friday, Christmas Day, and Boxing Day. Prospective visitors are strongly encouraged to check the official "Opening Times" calendar on the Westminster Abbey website before their visit, as the schedule is frequently adjusted to accommodate weddings, memorial services, and the various liturgical requirements of the Church of England.
