A black flag flutters high on the remains of a groyne extending a few metres out into the sea opposite the imposing bulk of St Thomas Church at Poonthura, a densely populated fishing village on the Thiruvananthapuram coast.
The flag, a local fisherman explained on Wednesday, is meant to remind people of the protests under way further south at Vizhinjam against the massive seaport being constructed by the Adani Group. Close by, several fishing boats have been dragged up on the church compound.
