Claim 4: “the monument was destroyed immediately after the war ended.”
DISPUTED
One source claims the monument was 'destroyed immediately after the war ended' to date the painting. However, Wikipedia and other sources describe the Feldherrnhalle as a permanent neoclassical loggia in Munich. It is likely the 'upper part' or specific Nazi additions to the monument were removed, rather than the entire monument being destroyed.
