19th to 20th century CE. Houses rare records of the ancient Mooppil Nair family, the legendary landlords who owned the palace and land under Valluvanad and erstwhile Cochin state. It was brought to attention in an article in ‘The Hindu’ in 2015. It once stood for royalty and grandeur but is now in an advanced state of decay. There is excessive vegetation growth in the eight-acre premises. The rare documents that throw light on the administration of the erstwhile Swaroopams and medieval history of Kerala are also in a state of neglect.

These Mills are located in Gurgaon, Mumbai. Once abundant with the life of Mumbai in the early 70s and 80s, these are now abandoned. They strongly showcase the rich culture and heritage of Mumbai then, and now they have embraced the rapid urbanization of Mumbai. Its hauntingly beautiful thick, stone walls, majestic arches, and imposing chimneys, now crumbling and covered with green, are still a sight to behold.

The building was the former residence of the Diwan of Baroda, Bhau Tambekar. It later took on the role of a school which was subsequently shifted. 

The 140-year old Tambekar Wada in the Raopura Area showcases three storeys of 19th century murals. The decaying but fascinating building is a window into erstwhile Maratha architecture. Built around a courtyard, there are two wings of the home – the front and the residence. Delicate woodwork and weathered paintings embellish the home. The paintings are done in the tempera on dry lime with the use of water-based pigments.
