The nearby mammisi is mostly crumbled, and has interesting reliefs of a series of Ptolemys. A small chapel on the grounds contains mummified crocodiles — the line to get inside can be a bit long. THey were found nearby, although our guide told us that they would indeed raise crocodiles here at the temple and mummify them after they died.
The temple is lit at night, although I would imagine that few boats spend the night here to allow people to see the temple. Nearly every visitor when we were there was from the road convoy.
