Directions to the Bayfordbury Site

The Observatory is located on a site off of Lower Hatfield Road (B158) which connects Hertford with Essenden. The Uno 341/641 Bus travels this route (timetable).

The entrance is opposite St Mary's Lane from Hertingfordbury, which is sign posted from the A414. The site is on a one-way road with an exit onto the B158 opposite the Riverside Garden Centre. If you reach the manor house, you've gone past the Site. It is on the right just before the house. This is highlighted on the site map here.
