 Some of Engel's later works are also characterised by the turn in central Europe to Gothic Revival architecture, with an emphasis on red brick facades typical for central Europe.The German Church (1864) is typical of that period, though designed by another two itinerant architects, the German Harald Julius von Bosse (who had worked much in St. Petersburg) and the Swedish-born Carl Johan von Heideken.In addition to churches, the neo-Gothic style was also dominant for the buildings of the growing industrial manufacturers, including the Verla mill in Jaala (1892) - nowadays a World Heritage Site - designed by Edward Dippel.
