Czechia is made of modest wooded hills, none of them quite high enough to see over the next one. For two hundred years the answer has been to build a tower on top and charge twenty crowns to climb the steps. There are hundreds of them, and collecting them is a recognised pastime: families keep stamp books.
They are also, almost by definition, exactly where a cyclist wants to end up. The top of a hill, a road or a forest track to the door, and a view that only exists because somebody built it. The oldest here is the minaret in the Lednice park, sixty-five metres of Romantic folly in a UNESCO landscape and the only one in the country.
The hills outlive the towers, and sometimes they win. Děd above Beroun was the first the Czech Tourist Club ever built, in 1893, and the forest it was raised above has grown up around it since, so the view from the top is now a gap in the trees.
