Sree Muthaliyarmadom Temple, located two kilometres east of Thodupuzha town in Idukki District, is an ancient temple dedicated to Lord Shiva. Situated on a picturesque hill near a stream, this temple holds great significance for devotees seeking wealth, salvation, and knowledge. The main deities worshipped here are Lord Shiva, Lord Vishnu, and Lord Rudran, along with other deities such as Ganapathy, Shree Sastha, Shree Mahakali, Shree Kamakshi, Shree Rashus, and Nagaraja. Historically, Cheraman Perumal Nayanar, the last Perumal, divided his kingdom into 18 regions, one of which was Keermalainadu, with its capital at Karikode. This land was renowned for its pepper and forest products. Initially ruled by vassals more of the Pandya kings, Keermalainadu later became part of Vembalinad and eventually Vadakkankoor. The early warriors of Keermalainadu were from the Arya community. However, after a conflict with a local leader, the king sought help from Vellalar warriors from Nanchinad and Venad regions to suppress the rebellion. These warriors, led by a Mudaliyar from Kochi, successfully conquered the land and settled there. Over time, they prospered as traders in Karikode, engaging in commerce involving jewels and textiles. As a reward for his service, the Mudaliyar was granted 25 acres of land by the King of Keermalainadu, where he established the Mudaliar Madom. The temple's origins trace back to a shrine built for Lord Venkitanathan by the Mudaliyar. Initially enshrined in a small structure near a pond, the idol was later moved to a temple within Mudaliar Madom after a fire. In the 16th century, following the annexation of Keermalainadu by Vadakkumkur, many Vellalars relocated to places such as Poovarani, Pala, Koothattukulam, and Erattupetta, while others remained as officials. During this period, Nasranis from Edatwa and Thripunithura migrated to Thodupuzha, and Tamil Nadu’s Parakkavetty Ushikha Rauthar became a leader in Vadakkumkur, bringing many traders with him. This ended the Vellalars’ monopoly in trade. In the 12th century, five Vellalar families from Tenkasi settled in Keermalainadu. Others arrived from Nanchinadu and Kumbakonam. The King of Kochi granted them favours, appointing them as custodians of revenue, forestry, armoury, treasury, and security. A significant historical structure in the region was the Annamalai temple, built entirely of granite in the Tamil style 1400 years ago. It housed 68 idols and followed Thevara-style worship. However, conflicts led to its abandonment. In 1965, the Department of Archaeology recovered the remaining idols, which are now preserved in a museum. To restore worship, a Shiva Lingam was installed in Mudaliar Madom. The Salagramalingam from Annamalai temple was also moved here, making it a unique temple with three sanctums: Lord Shiva in the north, Salagramalingam in the centre, and Venkitanathan (Vishnu) in the south. The temple's main festival is Shivaratri, celebrated in the month of Kumbham.
