Panoramic photos of Bulgaria's most beautiful mountain regions have been included in Google's Street View service.
Apart from nature, a number of buildings including museums and churches also have 360-degree photos offering viewers a glipmse on the inside.
According to the Bulgarian 360 magazine, a Google team climbed Musala, the Balkan Peninsula's highest peak, and many sites across the mountains Rila, Pirin, Stara Planina and the Rhodope Mountains to take pictures.
The Belogradchik Rocks lying in Bulgaria's north-west, which were declared Miracles of Bulgaria two years ago, and the ancient Thracian city of Perperikon are also among the sites that can be explored through the 3D photos.
