The correct option is 2 and 3 only.
Explanation
Sarais were roadside inns or rest houses constructed in medieval India to support the extensive network of trade routes and communication. They were a prominent feature of public works undertaken by rulers like Sher Shah Suri and the Mughal emperors to facilitate the movement of troops, merchants, and travelers.
Statement-wise Analysis:
- Statement 1 is Incorrect.
Sarais were not invariably built on a circular plan. In fact, the standard architectural plan for a Sarai was square or rectangular. They typically featured a large open courtyard surrounded by rooms on all four sides to accommodate travelers and their animals. While architectural variations existed, the circular plan was not the norm, and the use of the word "invariably" makes the statement factually wrong.
- Statement 2 is Correct.
The primary function of a Sarai was to provide temporary accommodation and security to travelers, pilgrims, merchants, and postal runners. They ensured safety on highways and provided basic amenities such as water, food, and fodder for animals.
- Statement 3 is Correct.
Sarais served as vibrant public domains. By bringing together people from diverse backgrounds-merchants, soldiers, and commoners-they facilitated cross-cultural interaction. They often functioned as hubs for the exchange of news, trade, and ideas, contributing to the socio-cultural integration of the empire.
Key Takeaway:
Sarais were essential medieval infrastructure designed for trade and travel, typically following a square or rectangular plan with a central courtyard, serving as hubs for accommodation and cultural exchange.
