Tegelen As the area is well known for it's centuries-old expertise in ceramics and pottery I took a trip to the ceramics museum located in a restored tithe barn on the beautiful estate of Kasteel de Holtmühle (17th century). This estate has been preserved (or restored?) and hosts the tithe barn, castle gates, gardens, ponds, moats and farmlands and all around the Kasteel de Holtmühle are nice walks to explore.
