The oldest parts of the Medelplana church date from the 1100s, with the tower added in the 1300s and the choir and armory coming later. At one time the church may have been dedicated to St. Helena (Elin) of Skövde and Götene. What is believed to be St. Helena's altar is currently the baptismal altar. In the village as it was in the middle ages, there was also a St. Helena's spring, which was later excavated and restored. It is situated by the road just north of the church.
Inside the south door stand two well-preserved lily stones from the 1100s. A gap where stairs used to be is on the church's north side, and an old box for contributions to the poor also is found there.
In 1611 the Danes were devastating the area, and among other deeds they burned the town of Skara. In Medelplana there was a pastor by the name of Jonas Andersson Grodt, and when he heard stories about how the Danes were causing havoc, he collected his own silver items and presumably the church's silver collection. According to a registry drawn up prior to the disappearance, the collection consisted of two silver goblets and a box made of silver for consecration wafers. He went off to the east from the parsonage in Medelplana, away to a little brook that flowed past the pastor's cottage at Kollängen. There he dug down and buried all the silver, so as to hide it from the Danes if they should come. Grodt died almost immediately thereafter, without revealing where he had hidden the silver treasure.
Many people have searched the treasury, but until now no one has found it. It is also thought that it may have been found and perhaps melted down, or that the entire story is a fabrication. The legend-encrusted silver treasure still sits brooding on its secret. It may be that some time in the future it will be discovered.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.
