After inheriting the manor of Greenwich, Gloucester enclosed Greenwich Park and from 1428 had a palace built there on the banks of the Thames, known as Bella Court and later as the Palace of Placentia.
The Duke Humphrey Tower surmounting Greenwich Park was demolished in the 1660s and the site was chosen for building the Royal Observatory.
His name lives on in "Duke Humfrey's Library", part of the Bodleian Library in Oxford, and in Duke Humphrey Road on Blackheath, south of Greenwich.
Duke Humphrey was a patron and protector of Oxford, donating more than 280 manuscripts to the University.
The possession of such a library did much to stimulate new learning.

Duke Humphrey was also a patron of literature, notably of the poet John Lydgate and of John Capgrave.
He corresponded with many leading Italian humanists and commissioned translations of Greek classics into Latin.
His friendship with Zano Castiglione, Bishop of Bayeux, led to many further connections on the Continent, including Leonardo Bruni, Pietro Candido Decembrio and Tito Livio Frulovisi.
Duke Humphrey also patronised the Abbey of St Albans.

Duke Humphrey's Walk was the name of an aisle in Old St Paul's Cathedral near to what was popularly believed to be Duke Humphrey's tomb, though, according to W. Carew Hazlitt, it was in reality a monument to John Lord Beauchamp de Warwick (died 1360).
This was an area frequented by thieves and beggars.
The phrase "to dine with Duke Humphrey" was used of poor people who had no money for a meal, in reference to this.
Saki updates the phrase by referring to a "Duke Humphrey picnic", one without food, in his short story "The Feast of Nemesis".
In fact, Humphrey's tomb is in St Albans Abbey.
It was restored by Hertfordshire Freemasons in 2000 to celebrate the millennium.

Duke Humphrey is a major character in two William Shakespeare plays.
His conflict with Cardinal Beaufort is portrayed in Henry VI, Part 1 and his disgrace and death following his wife's alleged sorcery is depicted in Henry VI, Part 2.
The portrayal of Humphrey is notable for being one of the most unambiguously sympathetic in the History plays; in Shakespeare's War of the Roses Tetralogy, he is one of only a handful of historical personages to be portrayed in a uniformly positive light.
Shakespeare portrays Humphrey's death as a murder, ordered by William de la Pole, 1st Duke of Suffolk, and Queen Margaret of Anjou.
He also appears as a minor character in Henry IV, Part 2 and Henry V.
He is the subject of two novels, Brenda Honeyman's Good Duke Humphrey and Juliet Dymoke's The Lord of Greenwich and his death is the subject of a 2003 mystery novel The Bastard's Tale, by Margaret Frazer.
