It is interesting to know when and where was the ancient town of Plovdiv founded. What is the place where the people settled and remained to live there for 8 millennia? This place is the hill known today as Nebet tepe situated on the hilltop plateau in the northern part of the three hills (Trimontium). The earliest settlements on the territory of the city are dated back to the 6th millennium BC. There were several prehistoric settlements on this territory, but the oldest and most important one was located on hill known as Nebet tepe. Initially the village was situated in a naturally sheltered and consolidated place on the front side of the northern hill. It gradually expanded towards the other hills to become the most significant Thracian city on the territory of Bulgaria. At that time the lands of today's Plovdiv were inhabited by the Thracian tribe Bessi. The scientists are still not sure if the name of the city at that time was Eumolpia or Pulpudeva. The complex of Nebet tepe continued to play an important role as an element of the fortification system of the city until the 14th century, with lots of improvements and supplements during the Antiquity and the Middle Ages. A notable finding of that later period is a reservoir of 350 cubic meters. http://www.visitplovdiv.com/en/node/521

The Holy Trinity Church and especially its tall belfry have become a symbol of Bansko as one of the most attractive mountain resorts, successfully combining the charm of its rich historical past and its picturesque location at the foot of the mighty Pirin Mountain with the most modern facilities for recreation – a wide choice of reputable hotels for all tastes and budgets, one of the best ski zone in South-East Europe. The Church dedicated to the Holy Trinity was built in the period of the Bulgarian National Revival. Its inauguration was made in 1835. The architectural plan of the church is a three-nave basilica or more exactly a pseudo-basilica with 44 m length, 22 m width and 12 m height. The walls are 1.1 m thick and entirely constructed of local ashlar, welded together by mortar. Large wooden beams of centuries old white fir (typical for the region) are used in the foundation and for leveling the walls. Part of the church is sunken under the ground level in order to look smaller from the outside and Turks can not get an idea about its real size. The altar piece is set within a skillfully constructed and decorated apse in the form of the half of a 18-angle prism with a remarkable stone cornice on the exterior. The roof is hold in the interior of the church by 12 massive wooden columns of white fir, symbolizing the 12 apostles. http://bansko-guide.com/attraction/holy-trinity-church/

The Archaeological Museum of Varna was established in 1887 by the brothers Karel and Herman Shkorpil (archaeologists and scientists of Czech and Bulgarian origin, founders of the Bulgarian archaeology and museum activity). The archaeological museum shows original finds from the Paleolithic Age /about 100 000 years BC/ to the Middle Ages /7th – 8th/ century, many of which are of great significance to the archaeology of Europe and the world. The largest Mesolithic collection of flint tools in South-East Europe, the largest collections of ancient terracotta, tombstone reliefs, lamps and glass vessels in Bulgaria are placed here. Unique exponents of the Hellenistic age, the Roman age and the Late Antiquity are presented; as well as rare premonetary forms, more than 2000 golden, silver, bronze and copper antic and middle age coins. Stone inscriptions from the history of the Bulgarian state are also presented; and also the largest in the country collections of early Bulgarian belt decorations and jewels dating from the Second Bulgarian Empire (1185 – 1393). http://visit.varna.bg/en/museums/preview/4.html

The oldest and best preserved monument of architecture since Roman times in Sofia is the rotunda church St. George. It was built in the beginning of the 4th century AD and, was considered, during the reign of the roman emperor Constantine the Great (reigned 306 – 337) and the flourishing of the ancient town Serdika (the old name of Sofia). It is believed that the rotunda is the oldest building in Sofia. The temple is situated in the courtyard of the Government Office, just a couple of meters of the remains of the ancient fortress Serdika. It is a cylindrical domed structure, built on a square base. Its width is about 9.5 meters in diameter and its height is about 14 meters. The altar room has a square form and four symmetrically placed niches. The main entrance is at the western wall. Originally the building was used for public purposes. After the recognition of Christianity as a religion in the Roman Empire, the rotunda became a baptistery (a building for conversion to Christianity), due to the many conversions, following the authorization of this religion. http://bulgariatravel.org/en/object/234/sofia
