Dowth is the least well known great passage tomb on the bend of the Boyne, Co. Meath. Roughly the same size as Newgrange and Knowth, Dowth has never been scientifically exacavated though previous botched attempts over the last two hundred years have left the mound considerably disfigured, with a massive crater in the top and large amounts of cairn material missing from the side. It had been used as a quarry for road building materials and long before that medieval souterrains were constructed using part of the north passage.
The south chamber has a short passage leading to a large circular chamber which was found to be aligned to the setting sun on the winter solstice. For some photographs of this event, click here
