Apart from being world-renowned as a botanical garden, Bangalore’s Lalbagh also has a rare tree fossil, Cacti Park and millions-of-years-old monolithic rocks.

Named ‘Peninsular Gneiss’ by the Mysore Geological Department about hundred years ago, Lal bagh's monolithic rock has been declared 'National Geological Monument' as inscribed on a plaque seen here. It is said to be one of the earliest rock formations on earth (dated three thousand million years).

Atop the rock is a watch tower built by Kempegowda II. It is one of the four watch towers built by Kempegowda.

Located opposite the band stand, Lalbagh's petrified coniferous tree, said to be twenty million years old tree fossil, (rock-tree) is one of the geologically precious collections brought from the Thoruvakkaru National Forest, South Arcot in Tamil Nadu. This well-preserved tree fossil in Lalbagh usually gets a casual look by visitors more focused on the Glass House and the gardens.

With more than thousand varieties of cacti, the Cacti Park of Lalbagh is lauded to be one of the largest gardens of its kind in the world.

This 6,000 sq.ft cacti house (mini glass house) open for public, has cacti and succulent varieties imported from countries like Brazil, Africa and Australia. There are many rare cacti species such as Gasteria, Spanish Dagger, Mammillarias.

It took nearly seven years for the Lalbagh Horticultural department to develop this Cacti Park.
