Tower house in the context of South Lanarkshire

The history of Ireland from 1169–1536 covers the period from the arrival of the Cambro-Normans to the reign of Henry VIII of England, who made himself King of Ireland. After the Norman invasion of 1169–1171, Ireland was under an alternating level of control from Norman lords and the King of England. Previously, Ireland had seen intermittent warfare between provincial kingdoms over the position of High King. This situation was transformed by intervention in these conflicts by Norman mercenaries and later the English crown. After their successful conquest of England, the Normans turned their attention to Ireland. Ireland was made a lordship of the King of England and much of its land was seized by Norman barons. With time, Hiberno-Norman rule shrank to a territory known as the Pale, stretching from Dublin to Dundalk. The Hiberno-Norman lords elsewhere in the country became Gaelicised and integrated in Gaelic society.

Castles have played an important military, economic and social role in Great Britain and Ireland since their introduction following the Norman invasion of England in 1066. Although a small number of castles had been built in England in the 1050s, the Normans began to build motte and bailey and ringwork castles in large numbers to control their newly occupied territories in England and the Welsh Marches. During the 12th century the Normans began to build more castles in stone – with characteristic square keep – that played both military and political roles. Royal castles were used to control key towns and the economically important forests, while baronial castles were used by the Norman lords to control their widespread estates. David I invited Anglo-Norman lords into Scotland in the early 12th century to help him colonise and control areas of his kingdom such as Galloway; the new lords brought castle technologies with them and wooden castles began to be established over the south of the kingdom. Following the Norman invasion of Ireland in the 1170s, under Henry II, castles were established there too.

Castles continued to grow in military sophistication and comfort during the 12th century, leading to a sharp increase in the complexity and length of sieges in England. While in Ireland and Wales castle architecture continued to follow that of England, after the death of Alexander III the trend in Scotland moved away from the construction of larger castles towards the use of smaller tower houses. The tower house style would also be adopted in the north of England and Ireland in later years. In North Wales Edward I built a sequence of militarily powerful castles after the destruction of the last Welsh polities in the 1270s. By the 14th century castles were combining defences with luxurious, sophisticated living arrangements and heavily landscaped gardens and parks.

Tower houses (singular: Albanian: kullë; Bosnian: odžak Bulgarian: кули, kuli; Serbian: кула, Romanian: culă) developed and were built since the Middle Ages in the Balkans, particularly in Albania, Kosovo and Montenegro, but also in Bosnia and Herzegovina, Bulgaria, Greece, North Macedonia and Serbia, as well as in Oltenia, in Romania.

Originating from the Mediterranean-Medieval stone tower houses, they were developed by Albanian carpenter-mason craftsmanship, which had a strong reputation within the Ottoman as well as the European elites for the construction of advanced residential housing. Mid-19th century studies pointed out that all the men – almost without exception – who build walls, fell trees and saw lumber in the European part of the Ottoman Empire and in the Kingdom of Greece, were from Albania, specifically from mountainous regions. For metal work Balkan Egyptians were contracted, and specific fortification features were sometimes left to stone mason specialists from the Adriatic coast.

The architecture of Scotland in the Middle Ages includes all building within the modern borders of Scotland, between the departure of the Romans from Northern Britain in the early fifth century and the adoption of the Renaissance in the early sixteenth century, and includes vernacular, ecclesiastical, royal, aristocratic and military constructions. The first surviving houses in Scotland go back 9500 years. There is evidence of different forms of stone and wooden houses exist and earthwork hill forts from the Iron Age. The arrival of the Romans led to the abandonment of many of these forts. After the departure of the Romans in the fifth century, there is evidence of the building of a series of smaller "nucleated" constructions sometimes utilizing major geographical features, as at Dunadd and Dumbarton. In the following centuries new forms of construction emerged throughout Scotland that would come to define the landscape.

Medieval vernacular architecture utilised local building materials, including cruck constructed houses, turf walls, and clay, with a heavy reliance on stone. Medieval parish church architecture was typically simpler than in England, but there were grander ecclesiastical buildings in the Romanesque and Gothic styles. From the early fifteenth century, the introduction of Renaissance styles included the selective use of Romanesque forms in church architecture, as in the nave of Dunkeld Cathedral. Castles arrived in Scotland with the introduction of feudalism in the twelfth century. Initially these were wooden motte-and-bailey constructions, but many were replaced by stone castles with a high curtain wall. In the late Middle Ages, new castles were built, some on a grander scale, and others, particularly in the borders, as simpler tower houses. Gunpowder weaponry led to the use of gun ports, platforms to mount guns and walls adapted to resist bombardment. There was a phase of Renaissance palace building from the late fifteenth century, beginning at Linlithgow.

Dundonald Castle is situated on a hill overlooking the village of Dundonald, between Kilmarnock and Troon in South Ayrshire, Scotland. Dundonald Castle is a fortified tower house built for Robert II on his accession to the throne of Scotland in 1371 and it was used as a royal residence by Robert II and his son Robert III.

Riomaggiore (Ligurian: Rimazzô, locally Rimazùu) is a village and comune in the province of La Spezia, situated in a small valley in the Liguria region of Italy. It is the most southerly of the Cinque Terre villages.

The village, dating from the early thirteenth century, is known for its historic character and wine produced by the town's vineyards. Riomaggiore is in the Riviera di Levante region. It has a shoreline on the Mediterranean's Gulf of Genoa, with a small beach and a wharf framed by tower houses. Riomaggiore's main street is Via Colombo, where numerous restaurants, bars, and shops can be found.

A yett (from the Old English and Scots language word for "gate") is a gate or grille of latticed wrought iron bars used for defensive purposes in castles and tower houses. Unlike a portcullis, which is raised and lowered vertically using mechanical means, yetts are hinged in the manner of a traditional gate or door and are secured either by bolts attached to the yett or by long bars drawn out from the wall or gateway.

Macroom (/məˈkruːm/; Irish: Maigh Chromtha) is a market town in County Cork, Ireland, located in the valley of the River Sullane, halfway between Cork city and Killarney. Its population has grown and receded over the centuries as it went through periods of war, famine and workhouses, forced emigration and intermittent prosperity. The 2011 census gave an urban population of 3,879 people, while the 2016 census recorded 3,765 people. The town is in a civil parish of the same name.

Macroom began as a meeting place for the druids of Munster. It is first mentioned is in 6th-century records, and the immediate area hosted a major battle c. 987 involving the Irish king Brian Boru. During the Middle Ages, the town was invaded by a succession of warring clans, including the Murcheatach Uí Briain and Richard de Cogan families. In the early modern period the MacCarthys took control and later the area found prosperity via milling. The MacCarthys built a series of tower houses, some of which survive. The family lost influence during the Williamite wars of the 1690s, after which authority over the town castle waxed and waned between the MacCarthys and a number of Anglo-Irish families.
