A unique sculpture dedicated to the memory of the famous native, astronomer Zdeněk Kopal, was ceremoniously unveiled on the occasion of his late 90th birthday on April 3, 2004. The sculpture by Federico Diaz and Marián Karel adorns Havlíčkova Street. More precisely, the place where the birthplace of this world-famous astronomer, a pioneer of the theory of close binary stars and the author of maps of the Moon, stood.
The restored sculpture of the binary is placed on a subtle carbon rod at a height of 3.5 meters above the ground. This location reinforces the idea of observing the starry sky from the earth, and the sculpture can be perceived against the sky thanks to the technological concept of using carbon fibers. The light panels mark the exact floor plan of the house where Zdeněk Kopal was born. At the same time, the text brings his lifelong scientific work closer.
