This curious little building the size of room is called Bank Pitis (if I remember correctly, translated literally as bank for money... Pitis... A Kelantanese slang for money). It is said the royalty (or was it the government?) used to keep their money there. Hard to believe isn't it?
Masjid Muhammadiyah, the main mosque of Kota Bahru. It used to be the primary Islamic learning centre in the Malay Archipelago especially when the famous Kelantanese saintly figure, Tok Kenali (died 1933) was still alive.
Ah... The pleasure of youth. If I don't know any better, I would have just joined and take a dip too... Haha! :]
