Top 10 Hidden Gem Cities to Visit in Europe

Matera, one of the world's oldest continuously inhabited cities, features cave dwellings first occupied 9,000 years ago, carved into a canyon in Basilicata. As 2019 European Capital of Culture, it draws 20% fewer tourists than Ghent, offering a quieter experience, with a typical sassi cave hotel costing 50 euros per night—30% cheaper than the average Italian historic city.

Ljubljana boasts Europe's most pedestrian-friendly historic core, car-free since 2007 with 90% of the old town accessible only on foot or by bike. Designed largely by Jože Plečnik, it earned the European Green Capital award in 2016, and its 300,000 residents enjoy a hilltop castle, the iconic Dragon Bridge, and a thriving café culture along the Ljubljanica River.

Plovdiv, founded in 4000 BC, is one of Europe’s oldest continuously inhabited cities and the European Capital of Culture in 2019. Its three hills showcase National Revival mansions, and the Roman amphitheatre hosts concerts and street art.

Kotor’s UNESCO-listed old town is enclosed by 4.5 kilometres of Venetian-era walls, culminating in a fortress reached by 1,350 steps. Set at the base of Europe’s deepest canyon-like bay, its Adriatic scenery rivals anything on the Dalmatian coast. Yet visitor numbers remain 70% lower than Dubrovnik’s annual 1.5 million, preserving an authentic, uncrowded atmosphere.

Valletta, the world’s smallest national capital at just 0.8 square kilometres, was built in 1566 by the Knights of St John. It packs more UNESCO-listed baroque architecture per square metre than almost anywhere in Europe, and its 2018 European Capital of Culture title spurred the acclaimed MUZA museum.

Sibiu, Romania, outshines nearly every other hidden gem on this list for its perfectly preserved medieval core, earning top marks as the most liveable city in the country for six consecutive years. Founded by 12th-century Saxon settlers in Transylvania and named European Capital of Culture in 2007, its allure is backed by the 96-hectare ASTRA open-air museum—the world’s largest ethnographic park, housing over 400 traditional structures. The Fagaras Mountains, just an hour away, provide unparalleled hiking access for over 50 trails, surpassing typical urban retreats.

Olomouc, Czech Republic, boasts the Trinity Column—a UNESCO-listed baroque plague column considered the finest in Central Europe, erected in 1754—which alone draws over 200,000 admirers each year. As the nation’s ecclesiastical capital, it features six baroque fountains and a 12th-century cathedral, all within a walkable 2-square-kilometer center. Rivaling Cesky Krumlov for beauty, Olomouc achieves this with half the visitor numbers, offering a peaceful alternative to crowds.
