This paper gives the principles of designing lightning conductor system for wooden sacral buildings i.e. churches and chapels. The new method of mounting the down conductors directly on inflammable materials was presented in the article of prof. dr St. Szpor and arch. Z. Hirsch entitled „The Protection of Monumental Wooden Buildings” published in this number of „Ochrona Zabytków”. Much attention has been given to designing the lightning conductor system as invisible as possible — a very important fact for monumental buildings.
