Spanish Square and Gimnazija Mostar, Mostar

Spanish Square is a five-minute walk from Old Bridge of Mostar. It is the main intersection of the city, quite different from the neighborhoods of the Neretva. The City Park, the Mostar High School Building (Gimnazija Mostar), City Hall, the Promenade, cafes, the theatre, and street art make the Spanish Square a place where everything and everyone intersect.

The Square is named in honor of 21 Spanish soldiers who died serving in the United Nations Protection Force in the Croat-Bosnian War. The Promenade of the Square was originally called Stephanie's Promenade for Princess Stephanie, wife of Prince Rudolf, son of Emperor Franz Joseph.

Spanish Square connects to the city's largest park, Zrinjevac Park, named for the Duke of Zrinski, a Croatian nobleman and general. The square and the park combine to make a vast peaceful recreation area.

The Old High School is another name for the Mostar High School. This enormous school building dominates Spanish Square. Built in 1902, it was the oldest and most exclusive school in Yugoslavia. For many years it was named for Aleksa Santic, a famous poet of Herzegovina. Today it is known simply as Old High School.

The Old High School is one of the few schools in post-war Bosnia to serve students from different ethnic groups. It was built in the Moorish revival style with a crenelated roof, Bosniak motifs, and warm colors. Like other buildings, it suffered damage in the Balkan conflicts, but it has been beautifully restored.
