Called the 'town of waters', it was a favourite royal resort in the Middle Ages, a reminder of which is the castle on Öreg ('Old') Lake. Today the castle houses within its walls the Kuny Domokos Museum, which traces the history of the region dating back to Roman times and displays a rich collection of archaeological finds and Tata pottery. An artificial ruin was built from the stones of the 12th-century Vértesszentkereszt Abbey in Hungary's first English park on the shore of Lake Cseke. The most famous of the water mills, once operated by the power of abundantly available water, is the Cifra Mill, the oldest monument of the town. The German Ethnographic Museum in the Nepomucenus Mill (1 Alkotmány utca) presents the artefacts and cultural heritage of the Germans of Hungary from the 17th century to the present day. The plaster replicas of ninety-six world-famous antique statues are on display at the Museum of Greco-Roman Replica Statues in a former synagogue (7 Hősök tere). The Geological Museum and the surrounding nature protection area at the foot of the Calvary Hill are interesting features. Layers of rocks in the abandoned quarry have preserved fossilised shells of 170 million years ago as well as a fireplace of pre-historic man. Next to the Calvary Chapel with Stations of the Cross is the 45-m high Fellner Jakab lookout tower. Fényes Spa, with its sports facilities, is worth a visit. Its water is supplied by spring-fed lakes protected because of their flora.
