The place where Tartini Square is located today, was once a harbour for fishing boats of Piran. The harbour used to be outside the town walls, because the oldest, partly preserved walls propagated behind the present Town Hall. The St. Peter Church stood and still stands outside, beyond the walls all alone since the year 1272. The church was restored in the year 1818. The new Court house was constructed on the western side of the square between 1885 – 1891.. In the year 1894 the harbour was filled in, due to bad smell, filth and for health and sanitary reasons, and a large square was built in front of the new Town Hall and Court House buildings. With the introduction of the electric railway, which connected the town with Portorož and Lucija in the years 1909 - 1953, a roundabout of oval-shaped tracks was laid on the square. The pattern of that scheme is repeated in the design of the present oval-shaped platform of the Tartini Square, made of white marble and designed by architect Boris Podrecca on occasion of 300th birth anniversary of Tartini.
The Tartini Theatre of Piran is created in around 1910 in mixed Historicist and Secession styles by Trieste architects. The building was renovated in 1998-2000. Various cultural events including concerts, exhibitions, film screenings and stage performances are organised here by Portorož Auditorium. The space is also used for conferences, symposia, seminars, presentations and receptions.
The Tartini Theatre has a capacity of 300 seats within an area of 350 square metres.

Next to Tartini Theatre there is probably the best party in town.
