Bhimavaram is famous for the temple of Lord Shiva that is about 1000 years old where He takes the form of Sri Someswara Janardhana Swami. Bhimavaram is considered as one of the "Pancharama Kshetram" (one of the group of five temples of Lord Shiva). It is said that the Shiva Linga here was installed by Lord Chandra and so the Lord here is called as Someswara.
The prominence of this temple is because of its uniqueness. One of the fascinating thing of this temple is that the colour of the Shiva Lingam changes on Pournami (full moon day) and on Amavasya (new moon day). Other uniqueness of this temple is that there is a temple of Goddess Annapurna just above the Garbha Griha of Someswara Swami, on the first floor. In the main mantapam, there are few steps that lead you to the temple of Annapurna on the first floor. You cannot see this feature in any of the temples in India. Another interesting feature of this temple is that there are five Nandis in front of the Shiva Lingam unlike in other temples where you find only one or maximum two Nandis.
The entrance of the temple is marked by a 15 feet tall pillar. In the prakara (compound) of the temple you can see idols of Lord Anjaneya Swami, Kumara Swami, Lord Surya, Lord Ganesha and the Nava graham. Inside the garbha griha you can see an idol of Goddess Parvati (consort of Lord Shiva). To the east of the main temple, there is a "Pushkarini" (sacred pond) called as "Soma Gundam" or "Chandra Pushkarini" because it is believed to be created by the Moon God (Chandrudu). On the ground floor and first floor of the temple there are two marriage halls where marriages are conducted. Even in the Goddess Annapurna Mantapam, marriages are conducted.
