Tunnel Day

The Austrian National Committee of the ITA (International Tunneling Association) organizes the Austrian Tunnel Day in conjunction with the Geomechanics Colloquium.

First, our tour leads to the beautiful late Gothic parish church of Gampern, where you can admire one of the three most famous Gothic winged altars in Upper Austria.

Then we go to Seewalchen where we visit the Gexi Tostmann traditional costume museum.

Afterwards we enjoy a walk on the promenade with a view of the lake, passing Villa Paulick, a historic summer villa that is a listed building.

A visit to the Klimt center in Schörfling, a walk on the Klimt theme trail, in the Klimt garden and a boat trip on Lake Attersee open up the Klimt trails and its impressive motifs on land and from the sea side.

Of course, lunch as well as coffee and cake are also provided.
