The Galtee Mountains in Ireland are mainly composed of Old Red Sandstone, which was formed around 400-350 million years ago during the Devonian period. The folding and uplift of these mountains occurred due to tectonic forces compressing the Earth's crust, resulting in the formation of the Galtee Mountains as we see them today.

Mountains don't lose height due to the continual upthrust caused by the plates coming together which caused them to form in the first place. Indeed, many if not most mountains are still growing rather than losing height.
