The legacy of the Marcher Lords left the area scattered with historic buildings including Norman castles, [[Cistercians|Cistercian Abbeys]], churches and medieval monuments.

The kingdom of Glamorgan was also notable for the number of castles built during the time of the [[Marcher Lords]], many surviving to the present day though many are now ruinous. Of the castles built during the medieval period, those still standing above foundation level include, [[Caerphilly Castle]], [[Cardiff Castle]], [[Ogmore Castle]], [[St Donat's Castle]], [[St Quintins Castle]], [[Coity Castle]], [[Neath Castle]], and [[Oystermouth Castle]]. Many of the castles within Morgannwg were attacked by forces led by [[Owain Glyndŵr]] during the [[Glyndŵr Rising|Welsh Revolt]] of 1400–1415. Some were captured, and several were damaged to such an extent they were never maintained as defences again.

When the [[Diocese of Llandaff]] became incorporated into the Province of Canterbury, the Bishop of Llandaff rebuilt over the small church with the beginnings of [[Llandaff Cathedral]] in 1120.<ref name="Newman39">Newman (1995), p.39</ref> In the western region of Morgannwg two monastic foundations were sited, a [[Congregation of Savigny|Savigniac]] house in [[Neath Abbey|Neath]] in 1130 and the Cistercian [[Margam Abbey]] in 1147.<ref name="Newman39"/> In the Vale a [[Benedictine]] monastery was founded in 1141, [[Ewenny Priory]], a community under the patronage of [[Gloucester Cathedral|St. Peter's Gloucester]]. The building of parish churches also began in the 12th century, densely in the Vale, but very sparsely in the upland and northern areas.
