5 secret jewels to discover in Europe

5 joyaux secrets à découvrir en Europe

L'Œil magazine has curated a list of five European cities rich in art historical treasures, highlighting hidden gems for cultural getaways. The first city profiled is Mainz, Germany, featuring the Romanesque-Gothic Mainzer Dom (Imperial Cathedral of St. Martin), the Gutenberg Museum showcasing the 42-line Bible as a landmark of printing history, and the Church of St. Stephen with its iconic blue stained-glass windows designed by Marc Chagall. The second city is Plovdiv, Bulgaria, where the old town blends ancient Roman ruins (a stadium, forum, odeon, and theater from the 2nd century) with 19th-century Bulgarian National Revival houses, such as the Balabanov, Hindliyan, and Kuyumdzhioglu houses, now converted into museums.

At a height of over 120 meters, the ruins of the former NSA listening station are home to around 2,400 m² of street art – Europe’s largest open-air gallery with over 400 works

An unfinished mountain in Berlin's Grunewald forest, built from the rubble of 400,000 buildings and once used as a Cold War listening station by the US NSA, has been transformed into Europe's largest open-air street art gallery. Since opening to the public in 2011, Teufelsberg now hosts over 400 works across 2,400 square meters, featuring artists such as El Bocho, Nina Valkhoff, Hera, and Dan Kitchener. The site operates as a curated exhibition space with admission fees, guided tours, and regular new commissions, and has been a listed building since November 2018.
