Both settlements used to be suburbs of town of Gorizia until 1947, when they become part of Yugoslavia while Gorizia remained a part of Italy. They have had a separate urban development since then. Nowadays, the Municipality of Šempeter-Vrtojba forms a single continuous urban area with the neighbouring towns of Nova Gorica and Gorizia. Since May 2011, these three municipalities have been joined in a common trans-border metropolitan zone, administered by a joint administration board.
