Mary Mathews Monument Celtic Cross

Louth is the site of an amazing and emotive structure known as 'the Celtic Cross'. The cross is a 7 metre (24ft) polished granite cross that dominates the cemetery on the hill overlooking the town. It was constructed by the founder of Louth, Thomas Matthews, who erected the monument as a perpetual memorial to his wife, Mary Mathews, who died in 1866.

Every year on the anniversary of her death, August 19, the sun reflects from the Celtic Cross to the front door - the spot where their house, The Retreat, once stood.

The monument is not only a testament to the love and devotion of a husband for his wife but also the accuracy of navigation technology in the 1800's. Its alignment was reportedly aided by one of the river boat captains of the Darling River.

Anyone visiting Louth can observe the occurrence and the locals have thoughtfully marked the places that visitors can experience the 3 minute light show.
