The KDHP Tea Museum is an industry and history museum situated in Munnar, a town in the Idukki district of Kerala in South India. Tata Tea Museum is its official name, but it's also known as Nalluthanni Estate where it is located or Kannan Devan Hills Plantation Tea Museum.
The country’s first ever Tea Museum located at KDHP’s Nullatanni Estate is just a five-minute drive from Munnar Town. The thousands of tourists who visit Munnar for sightseeing can carry home impressions of the distant past of this tea planting district in Idukki’s High Ranges. The aim of the Tea Museum is to depict the growth of this more-than-a-century-old tea plantation district. From the rudimentary tea roller to the present day, fully automated tea factory at Madupatty, the Tea Museum gives a first-hand knowledge about tea processing and the operations that go into the making of black tea. From the granite sundial made in 1913 by the Art Industrial School at Nazareth in Tamil Nadu that greets visitors at the entrance to the museum, the memorabilia preserved inside include an iron-age burial urn from the 2nd century BC that was exhumed near Periakanal Estate in the 1970s, the original tea roller of 1905, the rotor vane (the old-time CTC type tea processing machine), the Pelton wheel used in the power generation plant that existed in Kanniamally Estate in the 1920 and a rail engine wheel of the Kundaly Valley Light Railway that transported men and material between Munnar and Top Station during the early part of the last century.
