The project of the "Sun Plaza" complex in Astana city.
The results of archaeological researches prove that the ancient inhabitants of the Central Asia used solar observatories to determine the days of ritual sacrifices and holidays. The most well know in the Central Asia are the ruins of the ancient Uglugbek observatory. In Bereli place (Eastern Kazakhstan) remains of the construction of the Bronze Age lasted out which are similar to the oldest monument of the Bronze Age -Stonehenge. Of the variety of hypothesis of its origin the most probable one is that Stonehenge was a temple of Sun and represented the most ancient solar observatory. Owing to the special reciprocal placement of the flagstones ancient people determined the coming of equinox. Scientists noticed that only at daybreak of the longest day in the year a sunbeam can pass the construction throughout and illuminate the "altar".
Biologist and student of local lore V.Marikovskiy in one of his books reports about so-called "barrows with moustaches" in Central Kazakhstan - constructions using which ancient inhabitants of Kazakhstan determined the day of spring solstice.
Philosophic and world outlook basis of historically determined humanity attitude towards Cosmos, Sun, Earth, their gyre, necessity of understanding the nature of time are embodied in the project of the complex.
The main construction of the "Sun Plaza" complex - schematic model of the Solar System.
Eight radial pedestrian walks allow visitors to reach the round platform in the centre of which on the pedestal symbolic images of the Sun and planets are situated.
The pedestal consists of cylinders, placed on each other with reducing towards the centre of construction diameters and height 0,2m each. Diameter of the lower cylinder -90v, upper - 40m. In the aggregate cylinders form 10-step circular ladder, using which a visitor can get above the pedestrian zone to the "Sun". The surface of the pedestal is faced with the grey granite. Circular borders between the horizontal and vertical surfaces of the "steps" symbolize planet orbits.
The "Sun" represents a segment of hollow sphere of large diameter. Diameter of the segment on the level of intersection with the surface of the upper part of the pedestal - 15 meters, height - 3 meters. In the cavity under the framework electronic and illuminating equipment is located.
All of outer surface is covered with mosaic of granite bars of red, orange, yellow tint, between which plates of solar batteries are built-in.
Above the line of intersection with the pedestal along the circumference of the "Sun" numbers for 1 to 12 are located. These numbers are made of dull glass of orange
color and begin to shine brightly at the according hour (Astana time). For this purpose the energy of the Sun is used, which is accumulated by solar batteries even during cloudy days.
Above every digit there is a mosaic image of "protuberance", representing an ornament made of smaller than on the main surface slabs.
The second variant of the "Sun" contemplates that its surface will be completely faced with solar battery elements instead of granite slabs. Between these elements there are spaces, filled with the slabs of frosted glass of orange color, which let the illumination from the inner sources pass at the nighttime.
From the "Sun", along all the steps of the pedestal, 16 drawn triangles, laid with red, orange, yellow slabs, diverge, depicting sunbeams.
Along the axis of the "beams", at the places of their transaction from horizontal to vertical surface of the "steps", "planets" are located. Planet models represent hollow spheres, with 1,5m diameter each; "Saturn" is intersected by metal polished disc, depicting its rings. Under each planet at the pedestal there are inscriptions with the name of each planet. "Planet" spheres are faced with semi-transparent smalt and illuminated form beneath during nighttime. 20 meters away from the "Solar system", along the north-south axis the se
