Rock of Cashel

The Southeast combines medieval towns with a gentle hill and river landscape. Kilkenny, with its castle, cathedral, and the Medieval Mile, preserves one of Ireland's most intact medieval townscapes, Waterford dates back to a Viking foundation in 914, and the Rock of Cashel in Tipperary is home to the former seat of the Kings of Munster.The region is located on the way from Dublin to Cork and Kerry and is suitable for a stopover of one to three days. The Waterford Greenway is worth exploring by bike, a roughly 46-kilometre-long rail trail to Dungarvan on the coast.

Kilkenny in southeast Ireland is a city with approximately 27,000 inhabitants and one of the best-preserved medieval cityscapes in the country. It lies on both banks of the River Nore; it owes its nickname "Marble City" to the dark limestone of the area, and from 1642 to 1649, the Confederation of Kilkenny met here.The Medieval Mile connects Kilkenny Castle, a 13th-century castle with Victorian alterations and a freely accessible park, with St Canice's Cathedral (1202–1285), whose approximately 30-meter-high 9th-century round tower you can climb. Along the way are the Medieval Mile Museum, Rothe House, the merchant's house, the Black Abbey, and the Smithwick's Experience, dedicated to the city's brewing tradition.

Waterford is considered Ireland's oldest city; Norwegian Vikings traditionally founded it in 914. In the historic centre, the Viking Triangle, Reginald's Tower with an exhibition on the Viking Age, the Medieval Museum, the Georgian Bishop's Palace, and other small museums are clustered in a compact area.At the House of Waterford Crystal on the Mall, a guided tour demonstrates how the famous glassware is designed, blown, and engraved. Just outside the city, the Waterford Greenway begins, at around 46 kilometres, Ireland's longest railway line cycle path, leading over viaducts and through a tunnel to Dungarvan.

With a population of around 224,000, Cork is the second-largest city in the Republic of Ireland; its centre lies on an island between two arms of the River Lee. The covered English Market, a municipal market since the late 18th century, is the city's most famous food market.Overlooking the city is St Anne's Church in Shandon, while to the south rises the neo-Gothic St Fin Barre's Cathedral. Excursions lead to Cobh, the Titanic's last port of call in April 1912 and the departure point for around 2.5 million emigrants, and to Blarney Castle, about eight kilometres northwest, where visitors lean backwards to kiss the Blarney Stone.

Clonmacnoise on the banks of the Shannon in County Offaly is one of Ireland's most important early Christian monastic sites, founded by Saint Ciarán in 544. Remaining are the ruins of a cathedral, several churches, two round towers, and three high crosses.The original, approximately four-meter-high Cross of the Scriptures from around 900, is now protected in the visitor centre, with a copy outdoors. The site is managed by the Office of Public Works and is located south of Athlone, approximately halfway between Dublin and Galway.
