One of the most mysterious and least-known hillforts of the Klaipėda district, the Gerduvėnai hillfort, is hidden in the dense forests on the banks of the Minija north of Gargždai. Although it can be seen from the motorway, without knowing its exact location it is quite hard to tell its overgrown hill apart from other similar hills on the left bank of the Minija. The hillfort itself was built on the edge of an upland on the left bank of the Gerdaujė. Its slopes are steep, up to 35 m high, so anyone who wants to visit faces a challenging climb that ends at an oval area of 95 × 70 m on the top. Unlike most hillforts in the district, it is hard to make out clear defensive fortifications here, and only an expert will notice the remains of two ditches with a small rampart between them at the south-eastern edge of the top, and an outer bailey on the upland beyond, also fortified with a small rampart and ditch. It is said that on holidays, at noon and at midnight, an old man smoking a pipe comes out on top of the hill, or that something rolls down the hill into the Gerdaujė with a tremendous crash. That is all the scant information about this hillfort. In the fields at its western foot there is an ancient settlement, and 500 m to the south a burial ground from the 2nd–13th centuries. The hillfort itself is likely to date from a similar period.
