Kareng Ghar, Palace in Sivasagar district, India.

Kareng Ghar is a seven-storied palace at Garhgaon, about 15 km from Sivasagar. Its lower two storeys and upper five are built of brick, with a broad rectangular base, rows of arched niches and narrow windows, and a smaller tiered pavilion on top. Four lion gates (singha duar) give entry, and the structure measures 120 cubits by 30 cubits.

Sukhrungphaa commissioned the earliest constructions in 1698 AD. After the old palace was destroyed, Suremphaa (1751–1769) rebuilt it around 1752 as the present seven-storied structure. In 1751 Sunenphaa, son of Sukhrungphaa, had already built a brick wall about 5 kilometres long around the Garhgaon Palace and its masonry gate.

In Assamese, kareng means any royal palace; the 'ghar' in Kareng Ghar is an added word used here as part of one palace's name. The site is also called Ka-Rwan. Four entrances, known as Singha Duar (lion gates), lead into the building, and the Ahom dragon motif Ngi Ngao Kham appears in its carving.

The site is located near Sivasagar and is accessible to visitors who want to explore the remaining chambers and walls. It helps to ask for a local guide before visiting to better understand the structure and how it was used.

Inside the palace were hidden underground tunnels and passages that connected different sections of the building. These concealed routes revealed how the structure served as both a residence and a military fortification.
