Why Admiral Scheer's wreck was buried instead of broken up

Why was Admiral Scheer buried at Kiel rather than broken up after the war?

The bombed and capsized wreck was too costly to dismantle, so reconstruction of the area buried it where it lay.

Admiral Scheer's final disposition followed her wartime use in Kiel's defensive line. RAF bombing hit the ship and left the capsized hull beyond practical repair. Breaking up the wreck required money and effort that were not available for the task. The site was consequently filled over, leaving much of the ship buried beneath the later district rather than removed as conventional scrap.
