Goethe Tower – Frankfurt am Main, Germany

The Goethe Tower, located in Frankfurt’s city forest, was originally built in 1931 and stood as one of the tallest timber observation towers in Germany. After being destroyed by arson in October 2017, it was reconstructed between 2019 and 2020 following strong public demand for a true-to-the-original rebuild.

The new tower rises 43.3 meters and is built with 120 m³ (about 72 tonnes) of glued laminated sweet chestnut timber, including 48 circular columns, struts, and beams. Additional materials included 30 m³ of oak for steps, platforms, and railings, as well as 35 tonnes of steel for stair stringers and connectors.

RICON stainless steel connectors played a key role in securing the structural joints of the circular timber frame, providing both concealed strength and durability suitable for the outdoor conditions of Frankfurt’s forest. Prefabrication and timber framing began in April 2020, with the timber structure erected by July 2020.

Key Highlights:

Connector technology: RICON stainless steel connectors secured glulam joints in the circular timber frame.
Construction method: Reconstruction of a 43.3 m tall tower using glued laminated sweet chestnut.
Design features: True-to-the-original rebuild with round timber pillars and oak platforms.
Performance: Durable stainless steel connections designed for outdoor weather resistance.
Timeline: Groundwork began October 2019, timber erection completed July 2020.
Use case: Public timber observation tower rebuilt as a cultural landmark.

The reconstruction of the Goethe Tower shows how RICON stainless steel connectors contribute to long-span timber structures, combining modern durability with heritage preservation.
