Solan was originally the capital of the princely state, Baghat. A defining feature of Solan, is its ancient temples and monasteries. The Shoolini Mata Temple and Jatoli Shiv Temple are popular attractions for tourists. One of the most famous monasteries in this region is the Yundung Monastery. The hill-town is named after the Hindu goddess Shoolini Devi ~ who is a manifestation of Goddess Durga in Her warrior aspect. Shoolini, when translated literally, means 'the goddess wielding the spear'. Every year in June, a fair venerating the Goddess is held, featuring a 3-day melā at the central Thodo ground.

Solan is known for the production of quality mushrooms, as a result of the vast mushroom farming in the area, as well as the Directorate of Mushroom Research (DMR) situated at Chambaghat. Due to this fact, Solan is also known as the "Mushroom City of India". Solan is also called the "City of Red Gold", due to the bulk production of tomatoes in the area.

The city has one of the oldest breweries in the country, and also has a 300-year-old fort located at the top of a hill.

The history of Solan goes back to the era of Pandavas. According to local folklore, Pandavas lived here during their exile. In 1815, British won the Baghat state (now Solan) from the Gurkhas. Gurkha fort, or Arki Fort, is still standing tall on a mountain near to the city of Solan, and it is one of the historic tourist attractions of Solan. The town has been a capital of the princely Baghat State. The word Baghat is derived from Bau, or Bahu, meaning "many", and Ghat, meaning "pass". Initially, the state headquarters of the Baghat State was located at Bhoch in the Bhuchali pargana. The headquarters of the state was shifted to Solan, after the construction of cantonment in the city; the railway was set up in 1902. The evolution of Solan city can be understood in the following order or sequence:

Solan's history is intertwined with that of the erstwhile princely state of Baghat. The Solan cantonment is still the best, and the most well planned part of the area, hence buildings are made in a planned manner. The church in Solan cantonment is a heritage building, with wooden and stone carvings. It has sloping roofs and arches, reminiscent of British architecture.^{[citation needed]}
