two standing stones at Baltray, a coastal village located at the
mouth of the River Boyne, a place known in ancient mythology as
Colptha. The stones are situated on the edge of a ridge, overlooking
a raised beach towards the sea to the east. There were originally
three stones at the site, but now only two are visible. The stones
are slabs of shale, set 9 metres apart. Significant astronomical
and mythologyical discoveries have been made by Mythical Ireland
at Baltray. The first chapter of our book Island of the Setting Sun is devoted to Baltray and its significance to the wider astronomical landscape. See photos from the 2008 solstice sunrise here.
Star trails and standing stones
An amazing and beautiful image showing what astronomers call "star trails" over the Baltray standing stones made the front cover of the July 2008 issue of Astronomy and Space magazine. The photo was taken by Declan McCormack. See this spectacular image here.
Solstice sunrise 2000
astronomical alignment of the Baltray stones and Rockabill island
was witnessed on December 21st, 2000,
during a spectacular sunrise over the Irish Sea. Details and photographs
about this remarkable event are presented
During a visit
to the stones in 1999, it was discovered that the larger of the
two stones was oriented towards an island out in the Irish Sea
called Rockabill. This led to the revelation that the stone and
Rockabill marked the position of sunrise on the Winter Solstice.

sunset and moonrise
large standing stone marked the position of Winter Solstice sunrise,
it also marked the setting position of the sun on Summer
Solstice. At certain times of the lunar cycle, the moon's
rising position also coincides with that of the Winter Solstice
sunrise. The moonrise was observed
on July 17th, 2000 at Baltray.
our research we stumbled upon an ancient story which was told
in Skerries relating to Rockabill and
the sun god, Balor. This story, we believe, recalls the Baltray-Rockabill
solstice event and describes the sun's movement along the horizon
until it gets to Rockabill, its furthest rising point. Read
the myth here.
July of 2000 we made a startling discovery
about a strange alignment between the Baltray stones, a mound
near Fourknocks, and Rockabill. The alignment convinced us that
the monuments were intended to form part of a vast astronomical
device. The story of the amazing discovery can
be read here.
