Early in the 19th century, Maharaja Ranjit Singh, the first Maharaja of the Sikh Empire, took control of the Gobindgarh Fort. He renamed Gobindgarh Fort in honor of Guru Gobind Singh, the 10th Guru of the Sikhs. Later, between the years 1805 and 1809, he constructed new buildings and other improvements to the Fort. The majority of the renovations were based on French military fortification ideas, and Maharaja Ranjit Singh even sought the help of a French architect to complete the project. He strengthened the Fort primarily to defend the Golden Temple and Amritsar from attackers at the time.
Toshakhana Museum at Gobindgarh Fort is a structure that served as the treasury of Maharaja Ranjit Singh once. It is the place where he had kept the very famous and exclusive Kohinoor Diamond. Presently, it is a house of a coin museum, displaying a remarkable collection of old & some rare coins. One of the famous museums in Amritsar. The Kohinoor was housed here, and a recreation of the Kohinoor as it once was is also visible. They claim that no jeweler has been able to estimate the Kohinoor diamond’s value. Perhaps the most renowned diamond in the world is the Kohinoor, and the fact that it was kept here before the British snatched it away has piqued everyone’s interest in the fort.
It is one of the top Punjab tourist places in India due to a large number of visitors from all over the world. According to legend, Maharaja Ranjit Singh held a treasure in the fort that was guarded by 2000 troops and was valued at Rs. 30 lakhs (a kingly amount at the time), along with priceless diamonds, gold, and silver. The Royal treasury of Maharaja Ranjit Singh.
The Coins Museum in Amritsar is located in the Toshakhana at Gobindgarh. While the collection of coins inside is interesting (the silver and gold coins exist as replicas; the copper coins, which are fewer in number, are genuine), was the explanation about the Toshakhana itself. This is posted in the room which serves as a vestibule to the coins gallery, and is very interesting, explaining as it does all the features used like lightning conductors to insulate a powder magazine from accidentally blowing up.
