The Glass Chapel, dedicated to Our Lady, Maid of the Seas, first featured at the 1988 Glasgow Flower Festival. Following the festival, the then Parish Priest, Father Brian Logue, purchased the glass construction for Carfin Grotto.
The intention was to name the Chapel Our Lady, Star of the Seas, however during the construction of the glass Chapel in Carfin the Lockerbie disaster happened.
On the evening of Wednesday 21 December 1988, Pan Am flight 103, a boeing 747 aircraft named 'Maid of the Seas', travelling en route from London Heathrow to New York's Kennedy Airport, exploded above the town of Lockerbie killing 259 people on board the place and 11 people on the ground. The Chapel was therefore named 'Our Lady, Maid of the Seas' in memory of those who lost their lives in this tragedy.
The Solemn Dedication of the Chapel took place in June 1989 by Bishop Joseph Devine, Bishop of Motherwell.
Each day during the Pilgrimage Season, the Glass Chapel is open for Exposition of the Blessed Sacrament and is used regularly by Pilgrimage Groups for the celebration of Holy Mass.
