UP TO 30% of buildings flooded in Prague last week may have to be demolished because they have been critically weakened, the Czech government warned this week.
Large sections of Prague Districts One, Seven and Eight - the Strana, Karlin and Holesovice areas - remained cordoned off this week following the collapse of three buildings.
The picture is repeated from north-east Bohemia, bordering Germany, through Prague to central and southern Bohemia.
Flood waters, reached first floor levels in several parts of the capital, and rose much higher in towns and villages outside the capital, weakening foundations and lower storey walls.
In Prague, the River Vltava peaked at 6m above its average level, while close to the German border, the River Elbe was measured at 12.5m above its average height.
