The Dancing House is a building you have to walk past to see. A rigid stone tower stands beside a glass one that narrows at the waist and leans on wavy columns. Walk along the embankment and the two slide past each other, the glass one appearing to turn, so the building never presents the same shape twice. A photograph misses all of it. Frank Gehry called the pair Fred and Ginger, and the name stuck abroad.
Vlado Milunić, who lived next door, developed the design with Gehry and finished it in 1996, on a corner of the Rašín Embankment that had stood empty since a bombing raid hit it in February 1945. Václav Havel, whose family flat was on the same corner, backed the project, and the objections at the time were about putting anything modern on a nineteenth-century embankment at all. It holds offices, a hotel, a gallery and a bar on the roof, and the terrace up there looks up the river to the castle. From outside, the composition lines up best from Jirásek Bridge, right beside it.
