St Albans School is an independent school in the city of St Albans in Hertfordshire, in the South East of England.
 Entry before Sixth Form is for boys only, but the Sixth Form has been co-educational since 1991.
 Founded in 948 by Wulsin, St Albans School is not only the oldest school in Hertfordshire but also one of the oldest in the world.
 The school has been called "Britain's oldest public school" by the "Daily Mail".
 Nicholas Carlisle, in 1818, described the school as "of very ancient origin, and of great celebrity" and the "Good Schools Guide" describes St Albans as a "traditional public school, with a rich history".
The Alban Way is a cycle path in Hertfordshire, England, that has been constructed along the route of the former Hatfield to St Albans railway line.
 It runs from St Albans, close to St Albans Abbey railway station and the site of Roman Verulamium, through Fleetville and Smallford to Hatfield, ending close to Hatfield railway station.
 It is 7.5 mi long.
The St Albans Press was the third printing press set up in England, in 1479.
 It was situated in the Abbey Gateway, St. Albans, a part of the Benedictine Monastery of St Albans.
 The name of the printer is unknown, only referred to by Wynkyn de Worde in a reprinting of one of the St Albans books as 'Sometime schoolmaster'.
 He has sometimes been identified as John Marchall, master of St Albans School; however, a passage written by Worde in 1497 implies that the printer was deceased, and Marchall is known to have lived until 1501.
 Recent research has produced the name John Haule as a possible candidate for the Schoolmaster Printer.
 He presented the school with its first printed textbook, the "Elegantiolae", which was the first book printed at the press, and he was a printer, probably in St Albans in 1479.
Sopwell Priory (also known as Sopwell Nunnery) was built c. 1140 in Hertfordshire, England by the Benedictine abbot of St Albans Abbey, Geoffrey de Gorham.
 It was founded as the Priory of St Mary of Sopwell and was a cell of St Albans Abbey.
The St Albans Psalter, also known as the Albani Psalter or the Psalter of Christina of Markyate, is an English illuminated manuscript, one of several psalters known to have been created at or for St Albans Abbey in the 12th century.
 It is widely considered to be one of the most important examples of English Romanesque book production; it is of almost unprecedented lavishness of decoration, with over forty full-page miniatures, and contains a number of iconographic innovations that would endure throughout the Middle Ages.
 It also contains the earliest surviving example of French literature, the "Chanson de St Alexis" or Vie de St Alexis, and it was probably commissioned by an identifiable man and owned by an identifiable woman.
 Since the early 19th century it has been owned by the church of St. Godehard, but is now stored and administered at the nearby Dombibliothek (Cathedral Library).
 A single leaf from the manuscript is at the Schnütgen Museum, Cologne; one further leaf, and one further cutting, are missing from the volume, their whereabouts unknown.

The Hatfield & St Albans Railway was a branch of the Great Northern Railway which connected the Hertfordshire towns of St Albans and Hatfield.
 It opened in 1865 with the principal aim of allowing St Albans traffic to access the Great Northern's main line to London at , but soon came into difficulties when the Midland Railway inaugurated a direct route to London through St Albans.
 Passenger receipts declined in the 1930s, resulting in the temporary withdrawal of services in 1939.
 Passenger services were permanently withdrawn in 1951, leaving goods traffic to linger on until December 1968.
 Much of the route of the line is now incorporated into the Alban Way, a footpath and cycleway.
