Gurukul Jhajjar Archeological Museum is a place of pride for the town. It is the biggest museum in Haryana. The committed and passionate effort of Swami Omanand Saraswati in collecting antiques from various parts of the country brought this museum into being in 1959. The huge museum has antique coins and beautiful variety of idols.

The major attractions are idols of Panchwati’s deer statue (referring to Sita’s kidnapping), Lord Vishnu, and Lord Ganesha. Meticulously and tactfully made wooden chain with no joints and a unique 'flexible' stone are worth-seeing.
