Sofiya is the capital and largest city of the Republic of Bulgaria. It is located in western Bulgaria, at the foot of the mountain massif Vitosha, and is the administrative, cultural, and economic center of the country. Sofiya has had several names in the different periods of its existence. Remnants of the city's history can still be seen today alongside modern landmarks.

Sofiya is one of the oldest capital cities in Europe, blending its past and present in a remarkable architectural style. Historic landmarks include the 10th-century Boyana Church (one of the UNESCO World Heritage protected sites), the Alexander Nevski Cathedral (one of the world's largest Orthodox churches), and the early Byzantine Church of St. Sophiya.

More modern architecture is represented by the Bulgarian National Opera and Ballet, the Ivan Vazov National Theatre, the Rakovski Str theatre district, Slaveykov Square's outdoor book market, and the NDK, which is Southeastern Europe's largest cultural and congressional center.

Sofiya currently enjoys a booming film industry as it is the filming ground of several international film productions. Vitosha Boulevard, also called Vitoshka, represents numerous fashion boutiques and luxury goods stores and features exhibitions by world fashion designers.

Plovdiv is the second-largest city in Bulgaria, after Sofiya. It is the administrative center of Plovdiv Province in southern Bulgaria, as well as the largest and most important city of the historical region of Upper Thrace, famous for its ancient and diverse culture and millennial history.

The surrounding countryside is mostly bare, lacking major construction or landmarks, yet the city itself is particularly striking, since it, like Rome, has more than 200 known archeological sites, 30 of which are of national importance. Some of the world-famous sites include the Roman amphitheatre (early 2nd century A.D.) and stadium (late 2nd century A.D.), the magnificent colored mosaics of the villas, the Nebet Tepe archaeological complex and the noted samples of Bulgarian National Revival architecture, such as the Balabanov House, the Kuyumdzhiev House, the Lamartine House, and the houses of Georgiadi, Nedkovich, and Hindian.
