After completion of the School of building crafts he enters the atelier of the architect H. Wiethase, where he worked on the designs of churches and related equipment. From 1872 he studied architecture at the Vienna Academy and worked simultaneously in the atelier of the famous Austrian architect Friedrich von Schmidt. In 1875/76 he was in Italy where he met Bishop Jospi Juraj Strossmayer and Iso Kršnjavi, which led his life journey to Croatia. Already in 1876 he came to Đakovo, where Friedrich von Schmidt, after the death of the architect K. Rösner, took over the completion of Đakovo’s cathedral St. Peter. Bollé will, at first, only refine Schmidt’s designs of Đakovo cathedral, but will become later independent and take over a part of the project for Đakovo completely on his own. In the same year, as he came to Đakovo the first time he starts to supervise the restoration of the St. Mark’s church in Zagreb based on Schmidt’s plans. Schmidt entrusted him with the construction of the Academy building and the reconstruction of Zagreb’s cathedral, which is why in 1878 Bollé permanently moved to Zagreb. He immediately got orders from all sides and started the intensive architectural, social – cultural and educational activities.
He restored and built many buildings in Croatia in historic style (Museum of applied arts and crafts and Crafts school; the cemetary complex Mirogoj in Zagreb). In the spirit of romanticism he restores and renovates the pilgrim complex in Marija Bistrica (1878-1883), cathedral and the archbishop’s palace, as well as several Kaptol manors in Zagreb. After his designs the details of Zagreb city equipment were conducted, and he participated in all major issues of the urban design of Zagreb. The number of his works and projects in the field of applied arts is almost endless, from furniture, to theatre costumes and stage settings, stained glass windows, jewellery, tableware, lamps, etc.
Bollé's socio-cultural and educational activities are very extensive. He was an active member of the Art Society, he is one of the founders and directors of the Museum of arts and crafts and Crafts school, in which he, as part of it, founded also the Architecture school, which he headed for full 32 years. With students and professors he participated at large world exhibitions (Trieste 1882, Budapest 1885 and 1886, Paris 1900) where he won several valuable awards. Despite controversy because of his work, which also exists today, Bollé has undoubtedly played a crucial role in urban design of Zagreb in the second half of the 19th century.
