The town is located about 50 km away from Sliven on the way through the villages of Ichera and Gradets. There is another way connecting the two cities, which is about 18 km longer - through the Five-wheeler.

According to historical information, Kotel is a relatively new town - originated in Ottoman rule in the 14th-15th centuries, when refugees from nearby destroyed villages and fortresses settled there. Otherwise, the surroundings of Kotel were inhabited by the deepest antiquity, as witnessed by archaeological discoveries.
Throughout the centuries, after its creation Kotel strengthened and became rich thanks to the development of crafts. In the 18th and 19th centuries the city was an important cultural and economic center. Local craftsmen had the relative privileges provided by the fact that they supplied various goods for the needs of the Imperial army. The local fabrics and carpets were the most famous - even today, the Kotel carpets and tiles are a symbol of craftsmanship and beautiful patterns.
Quite naturally, the city's prosperity opened the eyes of the population to education and culture. The first secular school in Kotel opened its doors in 1812. The town still preserves its reputation as a Renaissance cultural and educational center, which gave to Bulgaria some of the most famous names in the education - Petar Beron, Georgi Sava Rakovski, Neofit Bozveli, Sofroni Vrachanski, Aleko and Stefan Bogoridi and others. The people of Kotel were also very bold revolutionaries - much of Hadji Dimitar's detachment was formed by Kotel's additions.
След Освобождението голям пожар унищожава по-голямата част от сградите, като оставя незасегнати само сградите в махала “Галата” в покрайнините на града. Днес в този квартал могат да се видят чудесно запазените стари възрожденски къщи. Останалата част от Котел също блести с красивите си сгради, но те са представители на архитектурата на късното Възраждане.
