Vyšehrad is a bluff where the Vltava turns, walled, and now mostly a park. You walk in through brick gates and come out on ramparts that open the whole river bend, with the city on one side and the water below on the other. Inside the walls are the twin neo-Gothic spires of the basilica of Saints Peter and Paul, the national cemetery beside them, and the Rotunda of St Martin, eleventh-century and round, one of the oldest buildings standing in Prague.
Czech legend puts the city's beginning on this rock: Princess Libuše, standing here, is said to have seen a settlement whose fame would touch the stars. The archaeology is less romantic, and the castle here is tenth-century, some seventy years younger than the one across the river. From 1061 to 1140 it was the Přemyslid seat, and Vratislav II, crowned Bohemia's first king in 1085, ruled from it. The gates and ramparts you walk are seventeenth-century, from its rebuilding as a Baroque citadel. Locals treat the grass as a lawn.
