Rheinberg (German: [ˈʁaɪnbɛʁk] ⓘ) is a town in the district of Wesel, in North Rhine-Westphalia, Germany.

After the town rights of Rheinberg had been granted to Archbishop Heinrich von Molenark in 1233, the construction of a city fortification began.

The waiter's shop was also built there in 1573 (Alte Kellnerei) It served as a grainstore for the income of the Amt Rheinberg and was used in the western part as a stables, but initially also as a dwelling of Salentin von Isenburg.

In October 1598, during the siege of Rheinberg by the Spaniards under Francisco de Mendoza, an explosion occurred in the Powder Tower, destroying large parts of the city and castle.

The western section was extended to two and a half floors as the apartment of the respective Schultheiß and waiter as well as the Electorate of Cologne officials, increasingly also the fortress governors, and equipped with larger window openings.
