In the late 20th century a new economic climate resulted in a renaissance of Irish culture and design, placing some of Ireland's cities, once again, at the cutting edge of modern architecture.Grange stone circle is the largest such megalithic construction in Ireland.The earliest date from the Neolithic or late Stone Age.
Newgrange in particular is more interesting in that the inner chamber uses corbelling to span the roof.
The chamber and passageway were usually contained in an earthen mound, with the chamber at the centre (Newgrange is again notable in having exterior stonework on the mound).
Other notable passage graves are Knowth and Dowth, also in the Boyne Valley near Drogheda.
The architecture of Ireland is one of the most visible features in the Irish countryside – with remains from all eras since the Stone Age abounding.
Ireland is famous for its ruined and intact Norman and Anglo-Irish castles, small whitewashed thatched cottages and Georgian urban buildings.
What are unaccountably somewhat less famous are the still complete Palladian and rococo country houses which can be favourably compared to anything similar in northern Europe, and the country's many Gothic and neo-Gothic cathedrals and buildings.Despite the off times significant British and European influence, the fashion and trends of architecture have been adapted to suit the peculiarities of the particular location.Such tombs consisted of a long chamber, with a large open area (or court) at the entrance.This "court" was generally marked out with standing stones, with the rest of the structure also built in stone.Passage tombs consisted of a central burial chamber, with a long passageway to the entrance.Again, standing stones were often used for the walls, with slabs of stone over the roof.
