Jantar Mantar of Jaipur is one of the five observatories constructed by Jai Singh II. Ujjain, Delhi and Varanasi are the other cities that house the remaining Jantar Mantars but there remain no traces of the one at Mathura.
Among the many instruments that are part of this observatory is the world’s biggest sundial. Jantar Mantar is located just a stone’s throw from City Palace and Hawa Mahal and features instruments made of stone and brass that were built using instrument design principles from ancient texts.
In all there are 19 instruments that help observe astronomical positions with the naked eye. Jantar Mantar is a fine example of Ptolemaic positional astronomy and has instruments that operate in each of the three main classical celestial coordinate systems: the ecliptic system, the horizon-zenith local system and the equatorial system.
When it suffered some damage in the 19th century, Major Arthur Garrett, an amateur astronomer who was posted as the Assistant State Engineer in Jaipur, undertook the first major restoration work on Jantar Mantar. As of 2010, Jantar Mantar has been included in the list of UNESCO World Heritage sites and remains a gem of Jaipur that cannot be missed.
During my travels round Laos in 2013 I visited Luang Prabang and visited Mount Phousi and enjoy the stunning views of Laos. I hope you enjoy it too!
Chiang Dao lies above the Menam Ping gorge on the green slopes of Doi Chiang Dao Mountain. The name means “City of Stars”, and derives from its earlier name Piang Dao, or “(at the) level of the stars”. True to the name, limestone peaks reaching a height of 2,186 m (7,174 ft) make Chiang Dao an impressive area. Chiang Dao is the third highest mountain in Thailand. The village is a quiet little picturesque area, with a quaint northern Thailand feel. It’s located in Chiang Dao national park. Chiang Dao is cover by fog almost of the year and temperature is always cool in winter and rainy season.
In 2013 when I was 2/3rds of the way through my trip across Central and South East Asia, I stopped in Chiang Dao for some rest and stunning scenery and It wasn’t disappointing. I walked along the Lisu tribe village road and deep into the country side. Along with visiting the famous Chaing Dao caves and the Phare Mahajadee Rachsamjammadhevesrivechai Temple both beautifully surronded by stunning Landscape. Nthing of course out does the Peake; Doi Luang Chiang Dao (ดอยหลวงเชียดางว)
