Back in Melaka, we later discovered that the island is a sort of a Muslim spiritual center where - according to some rumors - Christians were (still are?) killed. This would explain the presence of a Mosque in such a small island.
BTW, the place we passed the night in, was apparently part of a resort that closed in mysterious circumstances.
