Comprehensive conservation and restoration treatment of the summer and winter sacristies of St. Charles's Church (Karlskirche), covering the Late Renaissance to Baroque wood-paneled interior fittings, including furniture, wall paneling, and doors. Laser technology was used for surface cleaning; the findings were documented in a scientifically based study. The work also included the restoration of the historically significant wooden portal on the south side of the church with its richly forged iron fittings.
