Susiluola (Wolf Cave) is a crack in the Pyhävuori mountain. The upper part of the crack has been packed with soil, forming a cave. In 1996, some objects were found in the cave that brought about speculations that it could have been inhabited in the Paleolithic, 120,000 to 130,000 years ago. These objects, if authentic, would be the only known Neanderthal artifacts in the Nordic countries. However, there is disagreement as to whether Neanderthals actually settled in the cave.
Archaeologist have found about 200 artifacts, some 600 pieces of strike waste, scrapers and bolt stone, and heated stones from an open fire. The objects are made of various materials, including siltstone, quartz, quartzite, volcanic rock, jasper and sandstone; as siltstone and quartzite don't occur naturally in the area, at least some of these must have come from elsewhere.
The ground in Wolf Cave consists of at least eight layers, of which the fourth and the fifth are the geologically and archeologically most interesting. The stone material that has been found appears to have been worked with several different techniques - tools of stone with good processing structure, such as fine-grained quartzite and red siltstone, have been worked in a way that is typical of the Middle Paleolithic, probably from the Mousterian era, while quartz, other quartzite, and sandstone have been worked with the earlier Clactonian technique.
Large quantities of bones from mammals and their prey have also been found, mostly in the upper layers of the cave, though it is not certain that any of the bone material dates from before the last ice age.
Due the research work and falling boulders the public does not have access into Wolf Cave, but there is a walking trail about 1 kilometre long from the Tourist Center to Wolf Cave. The trail takes you past a rock garden, a bronze-age burial site and a "devil's field" (a moraine). The Wolf Cave Tourist Center is located on Paarmanninvuori hill in Karijoki, about two kilometres from the downtown area of Karijoki in the direction of Kristiinankaupunki. The Wolf Cave Tourist Center is open daily during the summer months.

The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
