The temple is a large, well-planned structure of mostly a single phase of construction. The temples's most admirable carvings are found in the panels located on either side of the entrance gateway depicting Ramayana scenes, Vishnu's incarnations and the puranic legend of
samudra manthan. To its west lies the Anaikulam tank used for bathing elephants, further west to which are the famous tanks of Chakrakulam and the Chettikulam, fed by perennial springs which do not dry even in summer—a key feature of Senji being its water works with dams and canals constructed by
Krishnappa Nayaka and his immediate successors. or in the 18th century by Rama Shetty under the Maratha Kingdom. The Chakrakulam was constructed by Muthyala Nayaka, who also constructed a mandapa beside the Venkataramana temple on a road leading to the
VarahaNadi and a temple of
Chakraperumal on its bank. Raja Design's cremation site is near the Chettikulam. Near the Chakrakulam is a big natural boulder with a hollow which served as the prisoner's well into which the condemned were thrown. To the east of the temple is the Kalyanamahal, an architectural treasure piece; which according to the MacKenzie manuscripts were built by one Krishnappa Nayaka, who was possibly
Tubaki Krishnappa Nayaka. The attractive monument, built in the
Vijayanagara style, is made up of a square court surrounded by rooms with verandahs on arches with stairways, in the middle of which is an 8-storey square tower with a pyramidal roof. The temple contains a number of inscriptions in Tamil which also refer to several structures built elsewhere in the Tamil country by other nayaks. Shrines of Goddesses are placed in the western corners of the temple, each with a small mandapa with a pier having multiple colonettes while another shrine with Narasimha and Krishna carvings is placed away from the middle of the western wall. ==Other structures==
