A short walk from the train station in Benešov, is Konopiště Castle. Like most things in the Czech Republic, it’s a perfect day trip if you just need to get out of Prague for a minute.
The main claim to fame of the castle is that it was the last home of Archduke Franz Ferdinand, aka the dude whose assassination kicked off the first World War. I honestly don’t even recall if we did a tour or not*, but my memories of the day spent there are that a cat followed us from the forest to the castle, and that the gardens were exceptionally lovely. I have a deep and abiding love of things that are symmetrical.
*This is what happens when they don’t let you take pictures inside.
