Risbebjerg is an archeological site containing both the remains of a Neolithic sun temple and Iron Age earthworks. Bordered by the Øleådalen valley, the site is marked by Iron Age earthworks consisting of semicircular ramparts 3 metres high and a dry ditch 2 metres deep, dating back some 2,000 years. There are also remains of a number of 5,000-year-old woodhenges, one of which has been recreated with stumps of wood in the original holes, giving an impression of the size of the ancient site. An observation tower provides information and views over the historic area.
The site was discovered in 1897, leading to finds near a spring of six flint axes and four flint chisels from the mid-Neolithic. The following year, a further 13 flint axes and two chisels were found, making it one of the principal sites for finds of flint axes and chisels. The fact that the finds were made near a spring indicated that the site had religious significance.
The site contains a number of ancient wooden circles from about 2,800 BC. Traces of the original wooden poles have been found and recently marked out with stumps of wood. From the clay pieces, burnt flint and burnt bones found on the site, it has been suggested that the circles may have served as a sun temple. They apparently supported a clay-covered platform, accessed by a flight of steps, on which experts believe fires could have been lit, possibly for sacrifices. Clay disks with ancient sun symbols have also been found, ritually buried under the poles. It appears as if the wooden circles were constructed over three separate periods.References:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
