Arco della Pace Utilizes LED Lighting from Thorn

The famous Arco della Pace (Arch of Peace) in Milan, Italy, among the most important neoclassical monuments in the city, now features LED luminaires from Thorn. A series of high-performance Thorn Contrast 2 LED floodlights was installed around the impressive “Arch of Peace” to accentuate the intricate details and fine craftsmanship. The lighting enhances the overall visitor experience and simultaneously saves electricity with increased efficiency.

The Arco della Pace brings together the past and the present in Milan. The granite structure with a marble finish represents the rich history and architectural heritage of the Lombardy regional capital. At the same time, the monument forms a distinct meeting place for both tourists and residents.

Work on the Arco della Pace, which Luigi Cagnola designed in honour of Napoleon Bonaparte, was first begun in 1807 and then put on hold soon after the defeat of the French leader at Waterloo. The arch was finally completed in 1838 on the orders of Emperor Francis I of Austria who dedicated the monument to the peace established between the European nations that attended the Congress of Vienna in 1815. Abbondio Sangiorgio sculpted a bronze statue of the goddess of peace with a six-horsed chariot (Sestiga della Pace) that stands atop the monument.

Lighting had to Emphasize Details of Arca della Pace

The Milanese authorities sought a new lighting solution that could provide clean, precise and efficient illumination for both the structure and the area around it. The new lighting installation had to tastefully emphasize the variety of architectural shapes and decorative elements, enhance the appearance of the urban space and increase the feeling of safety for the public.

To ensure the optimal light distribution and direction, 20 compact Contrast 2 fixtures from Thorn were placed on existing posts around the Arco della Pace. The fully adjustable LED floodlights were mounted on brackets that each feature a handy scale, which enables quick alignment and commissioning of the lights. A holographic optical filter redirects and focuses the light beam, allowing it to be rotated on its axis and aligned parallel to the structure, thereby helping to avoid parallax errors.

The 3000K color temperature emphasizes the warm pink tones of the marble. This chosen color temperature differs markedly from the cooler color temperatures normally utilized for public lighting. As a result of this contrast compared to other lighting in the area, visitors can experience a monument that appears to be visually separate from its urban surroundings.
