Gergeti Trinity Church stands alone on a ridge at 2,170 metres above the town of Stepantsminda, known as Kazbegi, in the Caucasus of northern Georgia, a fourteenth-century church of grey stone with nothing around it but grass and sky, and behind it rises Mount Kazbek, 5,054 metres of glacier and rock, so the church and the mountain make one picture. The church was built where it is to be seen and to be safe; in times of danger the treasures of the cathedral at Mtskheta were carried up here for keeping. The way up is the pilgrim path through Gergeti village on the far side of the river from the town, a climb of about ninety minutes through birch woods and open slope with the church holding the skyline ahead the whole way, until the ridge at its foot, and a road now reaches it too. Inside, the church is small and dark, with candles and old frescoes.
The mountain is the other half. Kazbek is a dormant volcano wrapped in ice, and long before any church it belonged to Amirani, the Georgian Prometheus, chained to the mountain by the gods for stealing fire and giving it to people; its real danger today is frozen, the Devdoraki glacier on its flank, which has repeatedly broken loose and thundered down into the gorge below. Before sunrise the first light turns the glacier cone copper-orange while the church and the valley stay in blue shadow, and for a few minutes the mountain looks lit from within; at night the lights of Stepantsminda scatter across the valley floor while the snow on the summit still holds the last daylight, and on clear summer nights the stars crowd thick over the ridge. Beyond the church the path climbs into bare, glaciated country toward the Kazbek glacier and the meteorological station where climbers sleep, and even a short push past the ridge trades the crowds for empty alpine quiet. Gergeti is a church put on a ridge to be seen from below, and the mountain behind it makes sure it is.
