Motijhil (also Motijheel, literal translation: Pearl Lake), also known as Company Bagh due to its association with the East India Company, is a horse-shoe shaped lake in Murshidabad, West Bengal, India.
 It was created by Nawazish Muhammad Khan, the son-in-law of Nawab Alivardi Khan.
 He also constructed a precious palatial palace beside this lake which is called the "Sang-i- dalan" (literal translation:stone palace) which is also known as the "Motijhil Palace".
 It is located at the bend of this lake.
 It was used as the residence of Nawazish and Ghaseti Begum, Nawazish's beloved wife.
 It is said that after Nawazish died, Ghaseti Begum lived here until Nawab Siraj ud-Daulah took over the palace and seized humongous amount of treasures in 1756 AD.
 With this money he built a similar lake with a beautiful palace, Hirajheel, on the opposite side of the Bhagirathi River.
 The palace has a lofty gateway, a mosque known as the ""Shahamat Jang"" and the "Kala Masjid" and some other buildings which were all built by Nawazish.
 This palace was built in 1740.
 As far as etymology is concerned, the palace has been named so as it was built using black basalt pillars which were brought from the ruins of Gaur.
 Thus, it was given the name of "Sang-i-Dalan" or the Stone Palace.
 This palace was then decorated with different varieties of flower plants and precious marbles.
 Inside the palace is a huge room having no doors or windows in it and closed on all the four sides.
 Some say that huge quantity of wealth belonging to the Begum had been kept hidden underground the room.
 Once labourers were employed to break open the masonry and excavate the treasure, but they ended up vomiting blood, so nobody dares to open it.
 The room is 65 feet long, 23 feet broad, 12 feet high plinth area, 1339 square feet.
