Old Town Square hosted Signal Festival until 18 October

Old Town Square hosted part of Signal Festival from 15 to 18 October 2026, bringing a public programme of light installations to Prague's historic centre. The central route reached the square and the Old Town Hall, linking the event with one of Czechia's best-known urban spaces.

The festival ended on 18 October, but its final day fell inside the current travel period. The programme combined outdoor projections with installations in public spaces across Prague, while a separate indoor section required tickets. The event's 2026 theme was Dream On - Dreams and Visions.

Signal Festival brought light installations to Old Town Square

Signal Festival ran on two routes between 15 and 18 October 2026, one in Prague city centre and one in Dejvice. The official programme lists 21 installations, including Svitlana Reinish's Living in Truth on the tower of the Old Town Hall. The mapping drew on ideas associated with Václav Havel and formed part of the central route.

A Prague news report said visitors on the central route moved between Republic Square, Old Town Square and the Faculty of Law. The report also recorded the festival's daily public programme from 7pm to midnight and identified the square as part of the route. The Signal Festival programme gives the dates, locations and installation details, while a report on the central route names the square directly.

The square's historic buildings frame the festival route

The square was founded in the 12th century and served as a marketplace at the crossroads of European trade routes. Its surrounding buildings include the Old Town Hall, the Church of Our Lady before Týn, the Baroque Church of St Nicholas, Kinský Palace and the Gothic House at the Stone Bell.

The setting gave the festival's projection a specific architectural context: Living in Truth appeared on the Old Town Hall tower rather than on a temporary stage. Prague City Tourism records that the square was declared a national cultural monument in 1962 and that its present name has been used since 1895. Its official history and buildings place the festival route within a square shaped by medieval commerce, later reconstruction and civic gatherings.

The link between the programme and the place was therefore more than a nearby listing. The projection used the Old Town Hall, a building that stands on the square's historic edge, while visitors crossed the surrounding pedestrian area to reach other central installations.
