Troisdorf

The city extends along the Sieg River between Bonn and Cologne, encompassing residential areas, industrial zones, and nature reserves across 62 square kilometers.

First documented in 832 through the mention of Sieglar settlement, Troisdorf expanded significantly in 1969 by incorporating neighboring communities Sieglar, Altenrath, and Friedrich-Wilhelms-Hutte.

The Picture Book Museum at Burg Wissem Castle presents permanent exhibitions of illustrations and narrative art, representing European children's literature through centuries.

The municipal administration provides digital services through an online portal where residents access waste collection schedules, register vehicles, and complete administrative procedures.

The city maintains a dedicated advisory council for foreign citizens since 1972, establishing itself as the first German municipality to implement this integration initiative.
