The church is one of the most beautiful art nouveau structures in this country. It has a thin spire and a simple stucco décor, while the interior is also somewhat sober. Each detail is, however, an excellent example of arts-and-crafts work.
The design of the structure, including the interior, was drawn up by the Jablonec architect Josef Zasche (1871–1957) and the construction work was realised by the company of Emilian Herbig. The official laying of the foundation stone took place on Saturday 18th August 1900 in conjunction with a celebration of the 70th birthday of Emperor Franz Josef I. The construction of the church was completed on 31st August 1902 and it was consecrated on Saturday 8th November. The church is surrounded by a number of sensitively resolved, neighbouring family houses in the early art nouveau style which constitutes a unique monument to modern European architecture. The house nearest to the church was conceived as the Old Catholic rectory and the group of so-called Scheibler Villas was built in according to designs by the Jablonec architect Robert Hemmrich (1871–1946).
The Church of the Exultation of the Holy Cross belongs to the Old Catholic Church. Regular masses are held there, as are occasional weddings, concerts and other cultural events. starokatolici-jablonec.cz
The interior is open to the public during the summer holidays on every Tuesday (from 10 am to 5 pm) as part of the Open Jablonec Churches festival.
