In a place called Sucheendram near Kanyakumari of India, Lord Brahma, Lord Vishnu and Lord Maheshwara are in a single form called 'Sthanumalayan' and worshipped in that form.
From Wiki:
The main deity of the temple is Lord Shiva, Lord Vishnu and Lord Brahma in a single form called Sthanumalyam. This 17th-century temple is famous for its architectural grandeur. The seven-storey white Gopuram is visible from the distance. Its 40 m facade is covered with sculptures of Hindu deities.
The place got the name of Suchindrum from the Sthala Purana. Hindu mythological legend has it that king of devas, Indra got relieved of a curse at the place of the main linga in the temple. The term "Suchi" in Suchindrum is believed to have derived from the Sanskrit meaning that stands for "purify". Accordingly, Lord Indra is supposed to visit the temple for performing "Ardhajama Pooja", or worship, at midnight every day.
