The town of Tryavna first became a regional centre in the early years of the XVIII century although there are earlier records, which indicate Thracian settlement in Tryavna. By the end of the XIX century, Tryavna had become the region’s main cultural and industrial town and was heavily involved in the development of crafts during the Bulgarian Renaissance period. This resulted not only to economic prosperity, but also to the creation of the Tryavna School - one Bulgaria’s oldest institutions of Art Tradition. Since that time, the work of Tryavna artists has become popular throughout the Ottoman Empire, Romania, Serbia and Russia.
Following Bulgaria’s independence in 1878, the Municipality started woollen textile manufacture and the first factory was opened in 1883. During the first half of the XX century a number of other types of industry were created, including the production of furniture, woodworking and textiles. The development of tourism started in the early 1920’s in Tryavna and Plachkovtsi and today there are a total of 1 250 beds. Tryavna also enjoys a moderate and healthy climate, (cool summers and mild winters) which resulted in a Sanatorium for Lung and Respiratory diseases being built in 1944.
The historical and architectural reservation in Tryavna is among its main attractions. Some of the best examples of buildings from the Bulgarian Renaissance period have been well preserved. The seven museum collections contain unique pieces of art from the late medieval period, such as icons and woodcarvings.
The town of Tryavna has preserved its old town square, the only one left in the country, which has been proclaimed as a Monument of Architecture.
