Verulamium / St Albans

Decided to explore St Albans today. I started off walking the Green Ring (extra) into the City Centre, where I had a coffee. I walked past a restored 15th Century building (Mid-Left) which is now a Thai Restaurant. I headed towards the Roman museum, and was distracted by the Six Bells pub (Mid-Right). After the museum I continued to the Roman Theatre of Verulamium (Top). The gatehouse (Bottom-Left) was nearby. I then walked back through the large Verulamium Park (Bottom-Right), and tried to follow the Green Ring back, however it was badly signposted.
