Sir William Herbert, Knight of
Raglan Castle, was granted the manors of
Tretower Castle and
Crickhowell just after the accession of
Edward IV in 1442. At that time this village was part of the
manor of Tretower. The land was then in the ownership of the
Earls of Worcester until the nineteenth and early twentieth century when much of Llangynidr was part of the
Glanusk Park estate. Until the 20th century, the principal language in Llangynidr was Welsh. For example, in his 1893 book 'Wales and her language', John E Southall, reports that over 60% of the population of Crickhowell and Llangynidr spoke Welsh, although the town was only a few miles from more anglicised Abergavenny. Welsh services persisted in at least one chapel in Llangynidr into the 1970s. ==Sport==
