Bee housing extraordinaire
The site is German and so had to be linked through google translation. But the pictues say it all even if not translated. Make sure to scroll all the way down, some of the best pictures are at the bottom of the page.
An arrow pointing to the right,within the text, will take you to different pages on the site. The first arrow leads to the trail in a botanical garden where that particular bee housing was built. You can see some of the flowers planted along the paths.
And if you search through there are some directions and ideas. If interested explore the site by clicking those right facing arrows.
