Kreuzberg, Hill summit in Friedrichshain-Kreuzberg, Germany.

Kreuzberg is a 66-meter hill in Berlin's Friedrichshain-Kreuzberg district that offers views across the city. The site sits within Viktoriapark and is accessed through multiple pathways that wind through the green space.

King Frederick William III of Prussia named the hill after the Iron Cross monument, which architect Karl Friedrich Schinkel designed and installed in 1821. This monument marked a turning point in how Prussia commemorated its military history.

The hill's name refers to the iron cross crowning Schinkel's monument, though some trace it to the cross-shaped ground plan of the structure. Since 1968 vines have again been planted on the northern slope, producing a tart wine called Kreuz-Neroberger that the district office gives only to selected guests and never sells. The humourist Adolf Glaßbrenner called it "Fahnenwein".

The summit is reached on foot: a broad path or stairway climbs straight up the centre of the slope from the street below. The northern slope is the steepest, dropping toward the glacial valley. The monument stands on an eight-metre podium raised in 1878/1879, so the last stretch to the top is via that base.

Since 1968 vines have again been planted on the north slope, yielding a tart wine called Kreuz-Neroberger. The district office gives it away only to selected guests; it cannot be bought. The humorist Adolf Glaßbrenner called it "Fahnenwein", joking that a single eighth tipped over a flag makes the whole regiment pull itself together.
