track leading to it from the High Street is flanked by an avenue of oaks planted in 1837 to mark the accession of Queen Victoria. From towards the east end of the High Street, and running to the east of the castle, is the Hereford Road. This was originally a turnpike road to Hereford, but is now just a country lane. At the north end of Broad Street, Bell Square runs to the west with more old buildings, then turns to the north-west as Meadow Street (B4230) to become the road to Kington. Bell Square is very wide for a street, and has been suggested as the core of the pre-13th century village arranged around an early marketplace or small village green. The west end of the High Street turns south then west as Mill Bank, named after an impressive mid 19th century brick corn mill but formerly known as Chamber Walk, and this becomes the B4230 road to Hereford. The mill is Grade II listed. The ancient parish church of SS Peter and Paul is oddly placed, away from the built-up area to the north and accessed by a country lane called Church Road which is a continuation of Broad Street. More unusually, this lane doubles back on itself after running round the churchyard and ends a short distance west of where it started, forming a dead-end hairpin loop. This has been suggested as the ghost of the pre-13th century village, arranged between the church and an early marketplace or small village green at Bell Square. A small grassy area is due south of the churchyard, and this used to be the town's bowling green. The B4230 does not enter the old town centre, but runs directly from Mill Bank to Meadow Street via a little bypass called Back Lane which roughly parallels Broad Street to the west. This is an old thoroughfare; the name in other mediaeval boroughs is known to indicate an access route to the back ends of a set of thin land strips called burgage tenements. One of these would comprise a town house with a smallholding at its rear, usually with back access so that farm animals didn't have to be taken through the house -hence Back Lane. The historical core of the settlement is a Conservation area. Two housing estates of the latter half of the 20th century more than doubled the size
