Ptuj is a town in northeastern Slovenia that is the seat of the Municipality of Ptuj. Ptuj, the oldest recorded city in Slovenia, has been inhabited since the late Stone Age and developed from a Roman military fort. Ptuj was located at a strategically important crossing of the Drava River, along a prehistoric trade route between the Baltic Sea and the Adriatic. The area is part of the traditional region of Styria and was part of the Austria-Hungarian Empire. In the early 20th century the majority of the residents spoke German, but today the population is largely Slovene.

Slovenia officially the Republic of Slovenia, is a country in southern Central Europe. Slovenia is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and a short coastline within the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of approximately 2.1 million. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced. Ljubljana, the capital and largest city of Slovenia, is geographically situated near the centre of the country.
