Submerged in the Vltava River, a 75-metre-long trough would pay poetic homage to Václav Havel, the Czech playwright and politician who spent many of his 75 years battling Communist oppression. Installed at a point triangulated between three Prague landmarks intrinsic to Havel’s life (the parliament, the theatre and his home), the volume would be drained by concealed pipes. Intrepid visitors could hire a boat, row over to the monument and step down into it, walking along the grate flooring to be at eye level with the river’s surface. Fourth-year student Libor Šenekel proposes cladding it in green quartz so the water appears evenly hued, rather than frothy white, as it cascades over the edges.
