This Hamlet is relatively modern, prior to the later 19th century it only consisted of a couple of farms. Its name is first recorded in 1410 as ''L'Dene
from Old English denu'' meaning valley. The valley its name is in reference to is that which the
A31 runs down. It has been postulated that the hamlet gave its name to an older name of the
River Alre as a record from 1447 describes the river as the
Denewater. The rivers current name is recorded for the first time over 100 years later in 1586. Hence it is theorised that
Denewater was one of the original names for the Alre as the river used to flow further up valley, nearer to the hamlet. The valley in which Ropley Dean is situated, still floods after raining and can occasionally bear a stream. ==The Anchor Inn==
