Exploring the theme of the Czech esoteric activities of the past was very difficult task at the end of the 20th century. Mostly because this specific area of research stood beside the main interest of professional historians. Documentary centre of the Czech Hermeticism fights this deficiency since 2001, led by its spiritus rector Mr. Petr Kalač. In almost 20 years, DCČH managed to bring the Czech esoteric heritage back to universities and greatly supported mass media interest in the subject. Furthermore, the centre mapped the broad field of modern esoteric activities and catalogued it for complex international research. Results of this work can be found at www.dcch.grimoar.cz.
