LED luminaires from Thorn are now illuminating the Arco della Pace, one of the most important neoclassical monuments in Milan. A series of Contrast 2 LED floodlights has been installed around the imposing “Arch of Peace” to pick out the intricate details and fine workmanship, improving the overall visitor experience and simultaneously saving resources by boosting efficiency.
Finding the right angle
Mounted on the 20 existing posts surrounding the arch, the compact architectural LED floodlights have been equipped with an additional optical filter to focus the light perfectly onto the architecture. The adoption of a primary optic with a beam angle of only 8° guarantees concentrated light, while the optic filter placed on top creates a thin rectangular distribution that complements the shape of the arch. Thanks to a filter holder that can be rotated, the light from every Contrast 2 LED fitting installed around the arch is projected parallel to the monument at all times.
Balancing architecture and safety
The Arco della Pace brings together the past and the present in Milan. The granite construction with a marble finish symbolises the rich history and architectural heritage of the Lombardy regional capital, while at the same time representing an important focal point and meeting place for both residents and tourists. This means that the site has to balance aesthetic considerations with issues of comfort and security – especially for the many people who visit the arch at night.
The Milanese authorities therefore looked for a new lighting solution that could deliver clean, precise and efficient illumination for both the monument and the surrounding area. The new installation needed to tastefully highlight the various architectural shapes and decorative elements, enhance the perception of the urban space and increase the feeling of safety for the public.
About Arco della Pace
Work on the Arco della Pace, designed by Luigi Cagnola in honour of Napoleon Bonaparte, was first started in 1807 and then promptly put on hold after the defeat of the French leader at Waterloo. The arch was finally finished in 1838 by Francis I of Austria and dedicated to the peace established between the European nations that attended the Congress of Vienna in 1815. The monument is topped by a six-horsed bronze Sestiga della Pace (Chariot of Peace) sculpted by Abbondio Sangiorgio and also features representations of the four rivers of the Lombardy-Veneto region (the Po, the Ticino, the Adige and the Tagliamento) in the form of reclining statues created by Benedetto Cacciatori and Pompeo Marchesi.
