Listed among the favourite sites of cultural tourism in Bulgaria are the Kazanluk tomb and the Sveshtari tomb, included in the list of the UNESCO-protected world cultural heritage. Of interest is the Alexandrovo tomb (near the village of Alexandrovo, Haskovo region) with valuable murals, the Mezek Thracian tomb (Haskovo region). Intriguing details of the building technique and artistic methods from Antiquity can also be identified in the remains of the royal Thracian cities of Kabile (in the vicinity of Yambol) and Seuthopolis (under the waters of the Koprinka Dam near Kazanluk), as well as in the Greek Black Sea coast colonies of Odessos (Varna), Apollonia (Sozopol), Messembria (Nessebur), Dionysopolis (Balchik), to mention just a few. Quite a few of which developed over old Thracian settlements.
