A very central attraction to Lenzburg is the castle atop a hill at the edge of the old part of the city. Lenzburg is accessible by SSB railroad, from whose station, a bus goes to the castle, through the city. The schloss (castle) was built over a long period of time, and reflects the changes within its walls. The various structures and towers provide a view into the various periods, in the museum collections/exhibits that one encounters there. There were some restorations and minor construction over the last 200 years, and as this was a strategic point, it is a castle that is fairly large, considering the various fortefi4ed houses and small castles in Switzerland; and the that part of Europe. From the ramparts one can see several other castles, similarly perched on tall hills--Wildegg among them (also in this region is the Hapsburg castle from where the future rulers of Spain and Austria, began). Lenzburg Schloss is definitely worth a day trip--and is a short rail trip from Zürich.
