Bad locations and brilliant design

The beautiful Octagon Room at Flamsteed House was created by Wren as part of his original Royal Observatory design, commissioned by Charles II. It was designed so that the Astronomer Royal could observe celestial events in the night sky. It's a rare example of a Christopher Wren designed interior. 

For this reason, the room has huge windows but the positioning of Flamsteed House was not ideal. This is because none of the walls were aligned with a meridian meaning positional observations were not possible. However, the Octagon Room remains of historical importance because it is one of the few Christopher Wren-designed interiors that you can see in London today. 

Entry is included with your ticket to the Meridian Courtyard and Flamsteed House. You can also hire the venue for events.
