Šempeter pri Gorici is a town and the administrative seat of the Municipality of Šempeter-Vrtojba in the Slovene Littoral region of Slovenia. There is a border crossing into the Italian town of Gorizia.

Gorizia, colloquially stara Gorica 'old Gorizia' to distinguish it from Nova Gorica, is a town and comune (municipality) in northeastern Italy, in the autonomous region of Friuli-Venezia Giulia. It is located at the foot of the Julian Alps, bordering Slovenia. It is the capital of the Regional decentralization entity of Gorizia and is a local center of tourism, industry, and commerce. Since 1947, a twin town of Nova Gorica has developed on the other side of the modern-day Italy–Slovenia border. The region was subject to territorial dispute between Italy and Yugoslavia after World War II: after the new boundaries were established in 1947 and the old town was left to Italy, Nova Gorica was built on the Yugoslav side. The two towns constitute a conurbation, which also includes the Slovenian municipality of Šempeter-Vrtojba. Since May 2011, these three towns have been joined in a common trans-border metropolitan zone, administered by a joint administration board.
