Irish megalithic tombs

[3] These tombs have an open east-facing entrance court which leads into a number of rectangular chambers (up to four).

Surrounding these chambers is a low dry stone wall with orthostats at the extremities.

Portal tombs (often referred to as dolmens) are mainly located in the northern half of the country.

In the majority of cases the tomb entrance faces the east towards the sunrise.

Their sloping roof and narrowing walls at one end produce their characteristic wedge shape.
