In Hyderabad, time calculation and importance played a significance role as history reveal ancestors, rulers of Hyderabad built several clocks across the city. Time management and time value was the prime motto of erstwhile Nizams ruling agenda. The historical clock towers constructed by bygone kings in the twin cities of Hyderabad and Secunderabad have been serving as one of the best tourist attractions for years now.
In today’s tech-savvy world where we constantly look at our phones or wristwatches, a clock may not be a sough-after gadget, but the heritage value of clock towers remains the same.
