Dating old welsh houses
An extra storey was added to the tower in 1815–1818 when Sir Robert Smirke re-fenestrated the castle and added Gothic Revival battlements.
Also on the Welsh border, close to Welshpool is Wattlesburgh.
Many of the English tower houses, such as Tattershall Castle or Buckden Palace are slightly later and larger than the Welsh examples, and built of brick.
Apart from tower houses there are a number of stone-built first floor hall buildings, where the hall is mounted over an undercroft.
Welsh tower houses, rectangular structures, consisting of two or more storeys, are closely related to those in Ireland and Scotland.
In 1976 Hilling produced a map (with listing) showing 17 examples.
Further apartment ranges were built round the SW court.
The two sets of apartments were approached by an impressive main staircase.
Most examples are found in southern Wales with a cluster of buildings in Pembrokeshire.
From about 1549 to 1559 these buildings were extended, by William Somerset, 3rd Earl of Worcester, particularly around the Pitched Stone Court and also with the long-gallery with its elaborately decorated Renaissance fireplaces.
The slighting of the castle in the English Civil War and its subsequent partial demolition make it hard to appreciate Raglan as one of the major domestic buildings of Wales.
Some of these such as Chirk Castle and Powis Castle have remained as houses, but others such as Raglan Castle in Monmouthshire and Carew Castle in Pembrokeshire are ruins which can provide some idea of their grandeur.
At Carew Sir Rhys ap Thomas from about 1480 onwards undertook a grand re-modelling including an almost entire re-fenestration with straight headed windows.
