World heritage site, The Srebarna Nature Reserve is located in the north-eastern part of the country, just two kilometres away from the Danube River and 120 km east of Ruse. The most prominent features of this reserve are its freshwater lake and numerous birds. Extending over 900 hectares, it is the breeding ground of almost 100 species, many of which are rare or endangered including, mute swans, great egrets, night herons, and the Dalmatian pelican. Some 80 other species also migrate and seek refuge here every winter. Roman and later remains have been found just north-east of the country’s biggest river lake at the fishing village of Vetren. Local people there preserve traditional customs and dress, and there is an old settlement of the ultra-conservative Old Russian Believers in Tatarista in the next village east.
