Vardzia is a cave monastery site in southern Georgia, excavated from the slopes of the Erusheti Mountain on the left bank of the Mtkvari River, thirty kilometres from Aspindza. The main period of construction was the second half of the twelfth century. The caves stretch along the cliff for some five hundred metres and in up to nineteen tiers. The Church of the Dormition, dating to the 1180s during the golden age of Tamar and Rustaveli, has an important series of wall paintings. The site was largely abandoned after the Ottoman takeover in the sixteenth century. Now part of a state heritage reserve, the extended area of Vardzia-Khertvisi has been submitted for future inscription on the UNESCO World Heritage List

Concertgoers dance at the Coachella Valley Music and Arts Festival in Indio, California, U.S., April 15, 2018. Coachella became one of the world' s premier music festivals not only for the A- list performers. The two- weekend party in the California desert has become a major event in its own right for the fashion. While designers have heavily marketed their brands to Coachella, the fans who draw the most notice often do so by embracing their own sartorial flair, driven by a sense of innovation and, among revelers in the searing heat, of inhibition.
