1. Landslide Kostanjek. Landslide Kostanjek is the largest (1.2 km2) active landslide in Croatia, located in the urbanized area (ca. 500 houses) in the westernmost part of the Croatian capital Zagreb. Landslide was initiated in 1963 by exploitation of Panonnian and Sarmatian marl for cement industry situated at the foot of the slope. It is reactivated, translational, and extremely slow to very slow landslide, with depth of ca. 60 meters. Sliding mass is ca. 32 million cubic meters. The landslide is equipped with a sophisticated monitoring system providing a better understanding of the sliding.
2. Zeolitized pyroclastics of the Donje Jesenje. In the northwestern part of the Hrvatsko Zagorje, at several locations on Maceljska Gora Mt., Lower Miocene volcanoclastic deposits have been discovered. The best outcrop of volcanoclastics is in the Donje Jesenje quarry. These sediments are result of submarine volcanic activity between the Egenburgian shelf and shoreface. Volcanoclastic deposits have variable primary composition, and contain various volcanic glass alteration products, including zeolites, clay minerals and SiO2 phases. Clinoptilolite is the most abundant zeolite in these deposits. Mordenite and analcime are also present. Clay minerals are represented by smectites and celadonite.
3. Glauconitic sandstones of the Vučji Jarek. The deposits of Macelj sandstones were formed in the shoreface under the influence of the tides. Macelj sandstones, some of them containing glauconitic materials, belong to the Vučji Jarek Mb., the lowermost part of the Macelj Fm. The Macelj Fm. deposits were formed in Eggenburgian and Early Ottnangian.
4. Trakošćan Castle and bedded conglomerates and sandstones of Trakošćan. One of the most attractive castles in Croatia dates back to the 13th century (although the first written mention of the toponym "Trakošćan" is dated to 1334). Together with surrounding buildings and forest park with a lake it is protected as a historical entity. The bedded conglomerates and sandstones from Early Miocen are located at the base of the southwest side of the Trakošćan castle.
5. Krapina Neanderthal Museum and Site Hušnjakovo is located near the world famous site of the Krapina Neanderthals “Hušnjakovo“. The exhibition is set up as a time machine through the history of the Universe, the Earth and Man, leading up to the present day, and lays special emphasis on the Neanderthal period.
