[1][5] Markapuram is notable for the Chennakesava Swamy Temple, built by King Sri Krishnadevaraya.

During Ratha Yatra (Tirunalla in Telugu) there occurs a popular carnival; the town is also famous for Chenna Kesavaswamy (Saptavahana Seva) on the day of Rathsapthami, which is attended by thousands of people coming from different parts of the state.

Due to this weather event, the partially-depleted ground water level increased significantly, leading to a marked decrease in local drought conditions.

The town's name comes from a story of a milk maid by the name of Marika who was graced with a son by Swamy Chennakesava.

Markapuram is situated about 100 km (62 mi) east of Kurnool and about three miles north-east of the Vijayawada-Guntakal railway line.

Markapuram is located at 15°44′N 79°17′E / 15.73°N 79.28°E / 15.73; 79.28 at an average elevation of 145 metres (476 ft) and is surrounded by Nallamala Forest.
