unior Open House 13.00 - 16.00. Talks at 11.00, 12.00, 15.00, and 16.00. Free tours throughout the whole weekend. Visit areas of the Old Royal Naval College not normally open to the public - Admiral's House, where the high-ranking officers of the Royal Navy used to reside, and the Undercroft, the last remaining part of the Tudor Palace in which Henry VIII, Mary I and Elizabeth I were born. As well as opening up these areas, there's plenty going on! Hear one of our talks in the Admiral’s House, attend a Guided Walk, or listen to one of our character actors - Joe Brown or Grace O'Malley - as they recount the stories of their past, and their relationship to Greenwich. Families can enjoy our Junior Open House. Be inspired by our decorative buildings, and design your own architectural artwork. This event is free, but all talks and tours require tickets. Obtain your free tickets from the Info Point on Lower Grand Square at the centre of the site. Children under 18 must be accompanied by a responsible adult. This event is free, but entry is on a first come first served basis, so it can't be guaranteed. You need to be registered to store the event information in your profile, but rest assured, we won't charge you a penny.
