It is seemingly an intrinsic part of human nature to find places sacred. Whether this is the tree you played around as a child, the caves beneath Delphi, or the rood screen's of Medieval Catholic Churches we understand that some places have a different intrinsic quality to them. There is often nothing rational about this, although certainly we can come up with both common traits and psychological speculation, they are more often than not simply a place we choose.
When we choose these places they may have rough utilitarian purpose that we make sacred by the attention we put on it, the store front church fro example, or we may layer them with finest work that human minds and hands can make. The best of what we are goes into such places. Where humans have long dwelt the landscape is often littered with the remains of those places, often used time and again by different faiths. The floors of many early Christian worship sites in Europe betray mosaics of earlier gods and goddesses - carefully converted into images of the Virgin or various saints.
We look at ruins and think of their antiquity, we forget that time is passing and what happened to them will happen to us.
Thus the link I have shared. Here an effort is being made to preserve the beauty of a temple from the ravages of climate change. A work that will be more than just the preservation of art, it is the preservation of culture, of prayer, of belief, and of that ineffable quality of place.
Think what a great treasure it would be to have the Temple in Jerusalem saved this way,or the Temple of Artemis at Ephesus, or even Stonehenge in working order.
Religion has three functions: Priestly, Pastoral, and Prophetic. Part of the Priestly function is not simply to lead and codify worship, it is to preserve and maintain tradition and value. Thus the preservation of sites of worship is ultimately a kind of act of worship itself.
