CC Madhya 12.73
guṇḍicā-mandira-mārjana-sevā māgi’ nila
When these three people came before the Lord, He begged them for permission to wash the temple known as Guṇḍicā.
The Guṇḍicā temple is situated two miles northeast of the Jagannātha temple. At the time of the Ratha-yātrā festival, Lord Jagannātha goes to the Guṇḍicā temple from His original temple and stays there for one week. After one week, He returns to His original temple. It is understood by hearsay that the wife of Indradyumna, the King who established the Jagannātha temple, was known as Guṇḍicā. There is also mention of the name of the Guṇḍicā temple in authoritative scripture. The area of the Guṇḍicā temple is estimated to be 288 cubits by 215 cubits (a cubit is about a foot and a half). The main temple inside is about 36 cubits by 30 cubits, and the kīrtana hall is 32 cubits by 30 cubits.
