Leinster

Leinster is an administrative province in eastern Ireland that encompasses twelve counties stretching from the Irish Sea coast inland. The landscape alternates between low valleys, rolling hills and agricultural plains, while larger towns and harbour settlements line the coast to the south and east.

This province originated from the Gaelic kingdom of the Laigin people who ruled much of eastern Ireland during the early Middle Ages. After the Norman conquest in the 12th century, several territories merged to form the current administrative unit.

The twelve counties display their own heraldic arms and colours during local Gaelic sports tournaments held across the region. Many place names throughout the area trace back to Old Irish and reflect ancient settlement patterns along rivers and coasts.

Travelers reach individual counties through several major roads and rail lines radiating out from Dublin in all directions. Coastal counties are well served by public buses, while inland areas often require a private vehicle.

Birr Castle Park in County Offaly houses a 19th-century telescope that once ranked among the largest in the world. Today visitors can view the restored instrument and walk through the extensive parkland surrounding it.
