Náplavka is a stone shelf a few metres below the road, running along the Vltava, and the city treats it as a floor rather than a view. You sit on the bare edge with your legs over the water, with the traffic out of earshot above you. On Saturday mornings a farmers' market runs the length of it all year. In the warm months boats moored alongside serve drinks and concerts happen on the paving.
The embankment wall behind you is hollow. Twenty vaults were cut into it in the nineteenth century, used for storing river ice and goods, then sealed when the quay became a car park. A reworking finished around 2020 opened them again as cafés, studios, galleries and lavatories. Several were given elliptical glass windows about five and a half metres across, weighing a couple of tonnes, which pivot open on a central axis like portholes. When the Vltava rises, all of it is shut and the vaults are sealed again.
