The grandly named Research Institute for Roses, Aromatic & Medicinal Plants houses this tiny museum, the one of its kind in the world. It's 3km north of centre up ul Osvobozhdenie; take a taxi (3 lv one way), or bus 3 from Kazanlâk’s main square. The photos and displays explain (in Bulgarian only) the 300-year-old method of cultivating the roses, picking their petals and processing the oil.
The attached shop sells rose oils, perfumes, shampoos, liqueurs, tea bags and jams.
