In 1252 April 11, Alard de Flemeng (Alard de Fleming) was supposedly granted, by Henry III, (In year 37 of his reign) a Royal licence to crenellate Pulberg (Pulborough)

"Grant to Alard de Flemeng, inasmuch as the houses and buildings which he had in the manor of Pulberg were lately burned by accident, that he may rebuild in his own territory, within his park of Pulberge, as he thinks best, with crenellating or fortifying.
[Cancelled.] Because otherwise below.
Grant to Alard le Flemeng and his heirs, as his houses in his manor of Puleberg were lately burned by accident, that they may rebuild in his park of Puleberg, where his ancestors used to inhabit, as he thinks best, without crenellating. By J. Maunsell. [King's chief councillor]"

Granted at Windsor,

Although this document has been considered by some as a licence to crenellate the current opinion rejects this as a licence to crenellate.

The canceled grant is dated 11 April and grant for a house without crenellation is dated 7 April. Presumably some clerical misunderstanding is the reason for this double entry. The two entries are on different roll membranes. However, someone thought a crenellated house was a possibility. Was this Mansel, over pressing his authority on behalf of his sister?
The old motte and bailey would seem to be the likely site as this is within the park, however there are a couple of small medieval moated sites in the area, although nearer the village and, therefore, on the edge of the park.

It should be noted that these transcription/translations often date to the nineteenth or early twentieth centuries and that unwitting bias of transcribers may affect the translation. Care should also be taken to avoid giving modern meaning to the medieval use of certain stock words and terms.)

Alard was married to Emma, sister of John Mansel, the king's chief or special councillor. He had served him 'as a squire until he was knighted by the king in 1251.' (ODNB) Alard was a younger brother of a long standing knightly family. The Fleming's had estates in Gloucestershire, which Alard inherited from his brother, but I don't know when he obtained Pulborough.
