Berlin – Albert Speer, son of the man who designed Adolf Hitler’s pompous Nazi Party rally grounds in Nuremberg, attacked Sunday a plan to declare the tourist-magnet complex a UNESCO world heritage site. Albert Speer senior designed the vast park as a place where hundreds of thousands of fanatical Nazis could worship Hitler as he spoke. It includes an avenue wider than an airport runway for parades and a vast, unfinished indoor congress centre. The municipality of Nuremberg, fed up with the cost of maintaining the crumbling, cracked buildings, decided last month to seek UNESCO recognition for a swathe of buildings as a heritage site, effectively handing over the problem to the international community.
