Wilhelmstraße is the boulevard of the Hessian state capital. Designed by Christian Zais, this magnificent street is lined with houses on one side and the Warmer Damm park on the other. Numerous boutiques and furniture stores have settled along the street.

Wilhelmstraße is also home to the Erbprinzenpalais – now the headquarters of the Wiesbaden Chamber of Industry and Commerce – the Kurhaus, the Hessian State Theater Wiesbaden, the Hotel Nassauer Hof, and the Reinhard Ernst Museum.

Wilhelmstraße runs from Kureck to Rheinstraße, forming the eastern boundary of the historic pentagon.
