Trier Prepares to Celebrate 40 Years as UNESCO World Heritage Site

In 2026, Trier will celebrate the 40th anniversary of the designation of the UNESCO World Heritage Site "Roman Monuments, Cathedral of St Peter and Church of Our Lady in Trier"; the inscription dates to 28 November 1986.

To mark this anniversary, the "Land" (state) of Rhineland-Palatinate and the City of Trier, in collaboration with many other partners, have prepared a year-long programme of celebrations, including various events, cultural offerings and initiatives that aim to connect the history, present and future of these unique buildings.

Ahead of the festivities, Chronicle.lu attended a press conference and had the opportunity to preview the upcoming programme.

Speaking to Chronicle.lu, Dr Heike Otto, Director General of Cultural Heritage Rhineland Palatinate (GDKE), said: "This year we are celebrating 40 years of UNESCO World Heritage Site Roman Monuments, St Peter's Cathedral and Church of Our Lady in Trier. Trier is internationally renowned for its exceptional monuments that bring to life the former splendour of a Roman imperial metropolis." Dr Otto extended an invitation to everyone to "come to Trier and celebrate this anniversary with us".

Elaborating on the programme, State Secretary Simone Schneider said: "The jubilee year 2026 demonstrates just how vibrant World Heritage can be: with a spectacular light show in the Basilica of Constantine, participatory Roman Weekends and renowned artists, from Giovanni Zarrella to Katie Melua, performing open-air concerts in the amphitheatre. A new Pixi book dedicated to Trier's World Heritage and a special HARIBO edition - offering the Porta Nigra as a gummy candy - also integrate this heritage into the everyday lives of families and children. In this way, we connect history to the present while simultaneously sparking enthusiasm for World Heritage."

Simone Schneider also emphasised the exceptional significance of World Heritage: "For 40 years, the UNESCO World Heritage site in Trier has symbolised a history of global importance and, at the same time, a lived responsibility. The unique density of its monuments, their international renown and the exemplary cooperation between the state, the city and the churches make Trier a true showcase for Rhineland-Palatinate."

Wolfram Leibe, Lord Mayor of Trier, stated: "Throughout the year, visitors can enjoy a diverse programme including exhibitions, light installations, concerts, family festivals and scientific lecture series. World Heritage connects us, makes us proud and reminds us that we are part of a long history. It is moving to see our city celebrate with passion and heart what makes it unique."

Dr Heike Otto later added: "World Heritage is not just a tourist attraction; it is an integral part of the city's identity - a jewel in the Rhineland-Palatinate cultural landscape, which will shine even brighter thanks to this jubilee." She said she was particularly excited about the return of the "much-loved" concerts in the amphitheatre, as well as the "now well-established" Roman Weekends, "which fascinate young and old alike".

Programme

The festive opening of the anniversary celebrations will take place on Saturday 31 January 2026, with a public ceremony in the Basilica of Constantine, the former audience hall of the Roman emperors and a central monument of Trier's World Heritage. The highlight of the evening will be the premiere of a special Jubilee lighting design by internationally renowned lighting artist Manfred "Ollie" Olma. Thanks to "state-of-the-art" laser technology, the basilica's vast interior will be transformed into an impressive contemporary light art installation, taking visitors on a visual journey through 2,000 years of World Heritage history - accompanied by a live improvisation on the basilica's monumental organ.

This installation can be admired not only on opening night, but also from Sunday 1 to Sunday 8 February 2026, every evening with free admission, and will be complemented by an open-air winter lounge area.

UNESCO

Since 1972, the UNESCO World Heritage Convention has obliged States Parties to preserve, for future generations, natural and cultural properties of outstanding universal value as the common heritage of humankind. Of the 1,248 World Heritage sites located in 170 countries, 55 are in Germany. With the inscription of the Roman Monuments, Cathedral of St Peter and Church of Our Lady in 1986, Trier has been part of this exclusive circle for 40 years.

According to the organisers, the Jubilee Year 2026 programme aims to celebrate this special responsibility, with everyone invited to discover Trier's World Heritage and come together to carry its spirit into the future.
