Friedenstunnel
From Wikipedia, the free encyclopedia
The Friedenstunnel (Peace Tunnel), formerly named the Rembertitunnel, is an underpass in Bremen's Schwachhausen district that runs below the Wanne-Eickel-Hamburg and Wunstorf-Bremen railway lines. It connecting Parkallee to Rembertistraße in the south.
The underpass was renamed on 6 September 2015 as part of the Peace Tunnel project. This initiative aims to promote peaceful coexistence among religions and cultures through artwork, texts displayed in the tunnel, and events fostering tolerance and understanding. The Peace Tunnel is intended to symbolize the cosmopolitan nature of the city of Bremen.

The Tunnel Project Community of Interest (Interessengemeinschaft Tunnel-Projekt) was the initiative of freelance graphic designer, artist, art teacher and lecturer Regina Heygster, who established the association Bremen Sets an Example of the Connection between Religious Communities e. V. on 16 October 2003. The association was renamed Friedenstunnel - Bremen Sets an Example e. V. on 14 March 2011. Her mosaic art is incorporated in the design of the Peace Tunnel.[1][2]
As a response to the attacks of September 11, 2001, Heygster contacted Bremen's religious communities, the Deutsche Bahn railway infrastructure management subsidiary DB Netz AG, and the Bremen City Hall in 2001 and 2002 with a proposal to set up a joint sign of peace. The busy Rembertitunnel was to provide the public space for the project.
The first Peace Tunnel model was created in 2002 and presented to religious communities at DB Netz AG, the town hall, and the chamber of commerce. In 2003, a walk-in model was developed and exhibited, with significant progress beginning in 2004 after the association's establishment in late 2003.
Installations
Following the exhibition phase in 2002 and 2003, implementation of the project began. In 2006, a large print banner was mounted on the Rembertitunnel Parkallee street-front, with several exchangeable tarpaulins that could be installed over the large banner. In 2007, the same was done on the An der Weide side of the tunnel entrance. Redesign of the tunnel frontage and interior was stepped up from 2007, when the tunnel structure was inspected prior to renovations. Work included sandblasting, application of dehumidifying plaster and painting, carried out on the Parkallee side in 2008 and the An der Weide side in 2009 and 2010. The first mosaic, Dove–Key Emblem, considered the symbol of the Peace Tunnel, was installed in 2008.
The Garden of the Religions was planted in 2009 at the Parkallee entrance and the concrete reliefs made for the two 3.2-metre-high (10 ft) mosaic peace trees Oak and Palm. The trees, at either side of the Parkallee entrance, were completed in 2010 and 2011. The An der Weide frontage was completed first, and was inaugurated in 2011.[3]
In 2012, the Tree of Life–Lotus Mosaic was built over the An der Weide entrance as a counterpart to the Dove–Key Emblem. It tops a message over the An der Weide entrance, "Understanding is the gateway to understanding - understanding is the door to understanding" ("Verstehen its das Tür our Verständigung - Verständigung ist das Tür zum Verstehen"). In 2013 a large banner was installed by the An der Weide entrance with the message "Peace starts small" ("Frieden fängt klein an").[4]
In 2014 and 2015, the tunnel interior was remodeled. Work involved wet abrasive blasting, sealing of the interior vault, side wall redesign and painting. In 2015, a 100-metre-long (330 ft) long peace mosaic frieze displaying the word "peace" in 135 languages was installed. 82 text panels featuring messages of peace and wisdom from different religions and cultures were designed. The tunnel lighting was redesigned, using LEDs to illuminate the vault of the tunnel to represent the arch of the sky and light the side wall mosaic.[4] The former Rembertitunnel was renamed Friedenstunnel at the official Peace Tunnel inauguration on 6 September 2015.[5][2]
