Monemvasia is located on a small island off the east coast of the Peloponnese in Greece. The island is linked to the mainland by a short causeway 200m in length. Its area consists mostly of a large plateau some 100 meters above sea level, the site of a powerful medieval fortress. The town walls and many Byzantine churches remain from the medieval period. The medieval buildings have been restored, and many of them converted to hotels.
Monemvasia’s nickname is the Gibraltar of the East or The Rock. The island of Monemvasia was separated from the mainland by an earthquake in 375 AD.

The Trou de Bozouls is a horseshoe shaped gorge, 400 m in diameter and more than 100 m deep, located on the territory of the commune of Bozouls, in Aveyron, France. This encircled meander has been dug by the erosive action of the current waters of Dourdou in the secondary limestones of Causse Comtal. The unique geography of the area came about 2 million years ago when glaciers advanced and receded. Humans have built settlements in the area for thousands of years, using the limestone rock to create their dwellings.

Breathtaking photos by Budapest-based photographer Tóth Tamás, capture Croatia’s winter landscape when the waterfalls freeze bright blue. The frozen waterfalls are situated in the National Park of the Kapela Mountains. They were formed over millions of years by what is known as the Karst process, the dissolution of soluble rocks including limestone, dolomite and gypsum. It is this that gives the water its electric blue color – appearing all the more dramatic when frozen.
