The aim of this paper is to provide secondary school teachers with a draft of a geological school field trip focused on rocks. It facilitates preparation of a petrological field trip that makes use of an urban environment.
The paper describes a route running through the New Town and the Old Town in Prague that enables pupils to learn about various rocks which are used as building materials for historical monuments (namely marlite, sandstone, granite, travertine, serpentinite, marble, and slate). Buildings that can be seen on this route were built in various historical periods.
