The old observatory "Jantar Minar" was found by the rajah of Jaipur. Some very ancient instruments for the sun and stars observation remained here. With their help astronomers can even predict eclipses.
The way to the observatory.
Tolstoy's street.
The ticket costs 250 rupees ( 5,5 dollars).
The sundial (Misra Yantra) was the first tool for time identification.
A shadow falls on the parapet and shows the current time.
Every instrument or building here has its own destination.
The memorable plate about the observatory foundation.
This is another instrument for time identification. It consists of a right-angled triangle and two arcs.
As big they are as accurate time is.
At night the North Star crowns these stairs.
But after the years of existence these constructions sank and their calculations became not so accurate.
The Ram Yantra is made for the identification of the zenithal distance and sun height.
These stone triangle walls are the end of the degrees scale.
With the help of that instrument ancient astronomers learnt about stars moving.
Jay Prakash Yantra is considered to be one of the most accurate instruments in the whole observatory.
All the rest instruments were constructed by using Prakash.
It helped to observe sun movements and zodiaŃ constellations.
This place has a special mysterious charm of the antiquity. And no one could even imagine that all these buildings were made without engines or computes that we use nowadays.
