As the Romans never conquered Ireland, architecture of Greco-Roman origin is extremely rare. The country instead had an extended period of Iron Age architecture.

A stylistic similarity has been remarked between these double monasteries and those of the Copts of Egypt. Gaelic kings and aristocrats occupied ringforts or crannógs. Church reforms during the 12th century via the Cistercians stimulated continental influence, with the Romanesque styled Mellifont, Boyle and Tintern abbeys.

Significant urban settlements only developed following the period of Viking invasions. The major Hiberno-Norse Longphorts were located on the coast, but with minor inland fluvial settlements, such as the eponymous Longford.
Castles were built by the Normans during the late 12th century, such as Dublin Castle and Kilkenny Castle, and the concept of the planned walled trading town was introduced, which gained legal
