PIRTON (31/2 miles N.W. from Hitchin) is an ancient village on the Beds border, said to owe its name to one Peri, who possessed it in Saxon times. William I. gave it to Ralph de Limesie, or Limesy, who founded the church and gave the tithes of it to the Abbey of St. Albans. The site of the castle built by Ralph is thought to be at Toot Hill, W. from the church, where a moat may be traced. The church was originally cruciform, but the transepts have long disappeared; the tower, massive and embattled, still standing between nave and chancel. Restoration has been carefully carried on recently; the tower was rebuilt in 1877, but some Norman work may still be traced in its arches. Note (1) monument and curious inscription to Jane, wife of Thomas Docwra (d. 1645); (2) double piscina, fourteenth century, in S. wall of chancel. Pirton should be visited for the fine old houses in its neighbourhood. _High Down_, S. from the church, is Elizabethan, with gables, twisted chimneys and mullioned windows; it was formerly the home of the Docwras. _Pirton Hall_, on a hill N.W. from the village, is also Elizabethan, and the _Rectory Manor House_ and _Hammond's Farm_ are both ancient. In the latter is some fine old carved oak. _Plummers_ is 11/2 mile S.W. from Knebworth Station, G.N.R. It consists of a few cottages. _Ponfield_ lies between Bedwell and Bayfordbury Parks. It is a small hamlet nearly 2 miles S.E. from Cole Green Station, G.N.R. _Poplar's Green_ is on the river Maran, on the W. edge of Panshanger Park. The old church at Tewin is less than 1 mile N.W. The station is Cole Green. _Potten End_ (2 miles N.E. from Berkhampstead Station, L.&N.W.R.) has a modern chapel-of-ease to Nettleden (1 mile N.). The hamlet is prettily situated between the rivers Gade and Bulbourne. PRESTON (4 miles W. from Stevenage Station, G.N.R.) is a hamlet beautifully situated on high ground. The Church of St. Martin is a small building a few yards W. from the green, a modern erection; close by is the Bunyan Chapel, and 1/2 mile N. is Bunyan's dell, where the author of the _Pilgrim's Progress_ often preached. _Temple Dinsley_, a manor house a little E. from the Red Lion, stands on the site of the preceptory of the Knights Templars, founded by Bernard de Baliol in the reign of Stephen. _Primrose Hill_ is a hamlet in King's Langley parish, 1/2 mile N. from the station, L.&N.W.R. PUCKERIDGE, a village on the Old North Road, nearly 1 mile S.W. from Braughing Station, G.E.R., was visited by Pepys on more than one occasion. Here, at the White Hart Inn, the road divides, going left nearly due N. to Royston and right to Cambridge. The village lies partly in Standon and partly in Braughing parish. The nearest church is at Standon, 1 mile S.E., but divine service is conducted in the church schoolroom. _Puddephats_ (3 miles N.W. from Redbourn Station, M.R.) is a hamlet in Flamstead parish.
