Sammallahdenmäki is a Bronze age burial site including 36 granite burial cairns dating back more than 3000 years, from 1500 to 500 BC. Sammallahdenmäki is an exceptionally valuable example of Finland’s Bronze Age culture because it presents the ancient monuments in a well-preserved natural milieu. It’s designated as the UNESCO World Heritage Site in 1999.
Two of the most spectacular cairns are the quadrangular "Chuch Floor" and the dike-like "Long Ruin of Huilu". A typical feature of the Sammallahdenmäki cairns are the stone cists, boxlike structures formed by stone flags standing on edge and forming end and side walls or only one or the other. The cist may have originally contained a body in a wooden coffin, or the dead person may have been wrapped in animal skins. On the other hand, the cist may also have served as a receptacle for the ashes of a cremation burial. Remains of cists are still visible in some of the unexcavated cairns as well as in one cairn reconstructed after investigations.
Direction signs guide the visitor to Sammallahdenmäki from Highway 12 (Rauma–Huittinen). At the township of Lappi, the route turns north along Road 2070. After ca. 3.5 km the route turns left along a side road marked by a direction sign. The route ends at an information sign.
The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
