A no fee thing to do in places I visited.
I have shared about The Ceremony of the Keys in previous posts. I’m revisiting this hundreds of years old ceremony as it is a free thing to do. Someone out there may be interested to check it out.
The Ceremony of the Keys is a gate-closing ritual at the Tower of London. This ritual has been going on for 700 years. Visitors may witness the ceremony rain or shine. It has never been cancelled. Everyone is escorted from the Tower gate at exactly 21:30. The ceremony starts at 21:52 and guests are escorted out at 22:05.
Photography is not allowed during the ceremony, but the guards don’t mind posing for a photo with visitors after.
Those who are interested to attend may reserve entrance tickets up to 12 months in advance online beginning this January. This service was not available when I visited London. I sent a letter with a self-stamped envelope requesting tickets 3 months prior to the visit and received my entrance pass in the mail. Instructions on the new application process can be found here.
