Once famous town named Sirmour was located about 16km. north-west of Paonta Sahib on the southern bank of the Giri.It was at one time the state capital known as Sirmour. Close-by lies a    tank  called  "Sirmouri Tal"  which   has  now   almost  entirely dried and  is   mostly   under   cultivation. It is believed that   the word   Sirmour   for   the   district originated from this   place. Amongst the ruins of this place is   the   store pierced with a deep hole lying on the top of a small hillock on the southern bank of the Giri.   In this hole, the pole is said to had been fixed for   the rope on which the   juggler   girl, on   whose   curse   the   Sirmour   town was destroyed, crossed   the   Giri.   A similar stone is on the other side     the river

Trilokpur  stands on an   isolated   hillock  about   24 km south-west of Nahan, 77-15’ north   and 30’30’ east, at an elevation of about 430 m. The place is famous for its temple of renowned  goddess Bala  Sundri.  Tfhe temple was built by Raja Dip Parkash in 1573.  A path connects it with the Nahan-Kala Amb Road at Sainwala, nearly 9.6 km below Nahan.  A road  runs  between  Kala   Amb and Trilokpur for a distance of 6.4 km.  A regular bus service runs from  Nahan to  this place via Kala Amb.  There is a large pukka tank outside Trilokpur village built by Kanwar Surjan   Singh  in  1867  in order   to  remove  the  then obtaining  scarcity of water in the village.  Now, a piped water supply scheme having been completed, the tank has  been  taken  possession  of   by  the  Fisheries Department  of  Himachal  Pradesh   for  fish  culture.  A branch post office, an ayurvedic dispensary, a GSSS, a patwar  khana, a  veterinary   dispensay, a  serai  and a forest chowki exist there along with a forest inspection bungalow. The  village is electrified.   The population of the village numbers 664 and its land covers an area of 742 hectares. 

An important fair is held at Trilokpur twice a year i.e.in the month of Chaitra and Asvina on sudi ashtmi to chaudas (from the 8^th to the 14^th of the bright half). During this period the people keep on coming and going but a mammoth gathering is seen on ashtmi and chaudas viz. the first and the final days.  The mela in Chaitra draws more people than that held in Asvina.

The Shivalik Fossil Park, saketi is situated amidst picturesque exposures of the Shivalik hills in the Markanda Valley, Sirmour District, Himachal Pradesh.   The Park has been developed by the Geological Survey of India, in collaboration with the Himachal Pradesh Government as a significant step towards preservation of Prehistoric animal sites, restoration of their natural environment and utilization of the same for scientific, educational and recreational purposes.  The Park inaugurated in 1974, displays life-size models of pre-historic

animals which thrived in the area 1 to 2.5 million years ago, the fossilized remains of which have been excavated from Saketi and adjacent areas.   Many spectacular fossil specimens of this collection belonging to vetebrate groups have been exhibited in a small museum in the Park.   In addition, the site has been developed to give a panorama of Plio-Pleistocene period (2.5 million years ago) through massive afforestation which has provided a green cover to the Park besides enhacing its beauty.

              The Shivalik rocks are famous all over the World for the embedded remains of various vertebrate animals and plants that flourished during a time span of 25 million years and evolved along diverging lines giving rise to the present day forms of land animals and plants.  The Shivalik fossil Park, Saketi, is one of the rare gifts of nature in Shivalik hills, wherein the remains of extinct prehistoric animals have been found preserved as fossils, and is a rich geological heritage.
