A looming fire is raging in the center of Berlin, the German capital. Bild says the fire broke out at the construction site. The fire broke out at the site of the Berliner Stadtschloss, or Berlin City Palace.

It is a castle under construction in the center of Berlin. The original town castle was completed as early as the 15th century. It was demolished in 1950, during the GDR. It is called the city castle, unlike many other castles in and around Berlin.

According to Bild, the fire started with a small explosion when the heater on the construction site went out of order.

A new version of the former ornate Prussian palace is being built on the castle construction site.

The first part of the Humboldt Forum is scheduled to open in September, originally scheduled to open last year.
