During my first visit in January 2004 heavy rain started and hindered me to explore all the treasures of Heldburg. This was unusual - normally the winter is great for winter sport in the Thuringian Forest and for visiting attractions such as castles, museums - except on Mondays.
So I visited only a bakery and some other grocery stores to get some food for a light evening meal with my son in his place in Siegritz.
This was always a nice and cheaper way than going out and not being allowed to have more than one beer when you have to drive.
If you stay in a B & B or a "Pension" how that is called do the same and purchase some of the local specialities. It is fun to try something different.

I came back again with Elizabeth in June 2005. We had great weather and were on our way to the spa in Bad Colberg which is only a few kilometers away.
She was impressed by the medieval town gate through which still all the local traffic flows. It is considered to be a landmark.
Heldburg and its surroundings were a so called "Sperrgebiet" during the communist system. That meant many restrictions applied for travellers and locals because of the close border to West Germany. Sometimes complete villages were torn down.
I got the feeling that many locals already forgot about all these bad things, they only remember what was eventually better than now, such as employment and child care.

Their are so many great looking buildings in Thuringia that it is impossible to show them all. It would also become boring after a certain time. Try to catch impressions from everything. Learn also about the people. Don't be afraid to go in small local restaurants and go through the adventure of ordering something which you don't know. Sit together with people who do not speak your language. I did so in Japan and hat a great time. I got even free samples of many things. In Thuringia I got free schnapps.
