Top 15 things to do in Koper
1. Koper Cathedral and Bell Tower

See one of Slovenia's oldest bells and take in excellent views of the bay at Koper Cathedral and Bell Tower, whose simple exterior with Romanesque, Gothic, and Renaissance elements belies a luxurious Baroque interior. A large oval window above the main portal dominates the facade plated with white marble. Built in the 12th century, the church and the tower were restored on several occasions. The four-story tower holds a bell from 1333; for a small fee you can climb to the upper terrace and enjoy panoramic views of the bay. Admire the 18th-century Venetian-style frescoes adorning the interior walls of the church, and behind the altar don't miss the 14th-century chiseled sarcophagus of St. Nazarius, featuring the image of the bishop on the lid.

2. Praetorian Palace

The Praetorian Palace is a 15th-century Venetian Gothic palace in the city of Koper, in southwest Slovenia. Located on the southern side of the city's central Tito Square, it houses the Koper city government and a wedding hall. It is considered one of the city's architectural landmarks.HistoryAn earlier municipal hall existed on the same site by 1254, before the square itself Work on a new building began after the original was destroyed during a major revolt in 1348, but the incomplete building was again destroyed in 1380 by a Genoese raid that sacked and burned the city in that year. The current structure dates from the mid-15th century, having been begun in 1452-1453.The left wing and the portico leading from the square to the colorful via Calegaria were the first to be completed, while the right wing dates from the 1480s. In 1505, the Porto del Corte was added; the renaissance gateway supports a small terrace and connected the Praetorian Palace with the Foresteria.The external staircase facing Tito Square was completed in 1447. In 1481, Giovanni Vitturi replaced peaked gothic windows with semicircular renaissance ones. The arms of the city governors on the facade attest to the fact that the balustrade was not completed until the beginning of the 16th century. The center of the crenellated portico features a statue of Justice. The main facade took its present shape in 1664, when a thorough renovation rearranged the numerous plaques and arms set into it. Additional ornaments and signage are fixed into the palace's Cobblers' Street wall, testifying to its status during the time it served as the seat of the city podestà, the Captaincy, and the Grand Council .

11. Tartini Square, Piran

Sitting close to the water's edge, paved with white marble and surrounded by elegant 19th-century buildings, Tartini Square serves as the largest square in town and a hub of activity. The square was part of the harbor until 1894, when it was filled in and mounted with a statue of violinist and composer Giuseppe Tartini, after whom the square is named. Most of the buildings are older than the square itself; be sure to look for the Gothic house, the only building that has preserved its original exterior. The square's distinctive oval shape comes from the time when it served as an electric railway station; today it's a pedestrianized zone. Relax with a beer, have a bite of pizza or pastry at one of the outdoor cafes, and watch the locals go about their daily lives.
