Halil Bey Mosque (Old Music)

This striking Ottoman mosque, painted in vivid red brick, sits right in the heart of Kavala's old peninsula near the fortress — and it was once the city's main place of Islamic worship. You can still spot the remains of the minaret, and next door a small informal folklore museum run by the local cultural society adds an unexpected layer of history. It's a quietly fascinating stop that connects the city's layered Ottoman and Greek past in one compact spot.
