Indian Railways- Indian Railways was founded in 1853. Karim's Hotel- This hotel was established in 1913. It is world famous for serving lip-smacking non-vegetarian food. St. Thomas' Boys' School- This school was established in Kolkata in 1789. Well, that's really historical. Indian Postal Service- It has been operating since 1774.
I love interesting facts like that! That's super interesting about the postal service to me, actually. I enjoy writing and receiving letters and I've had a few pen pals from around the world in my time, so it's just a cool fact to me that the Indian Postal Service has been operating for so long.
