Poles are conservative so nudism has never been as popular here as in other countries, e.g., Germany. Still, nudist movement gained a lot of supporters in communist times, despite the wishes of communist authorities.
Chałupy became famous in early 1980s when this small seaside village was proclaimed the capital of Polish nudism. Local residents weren`t too happy because it happened that nudists appeared in their bare garb in the centre of the village, e..g., going shopping. Communist authorities tried to ban or at least contain the trend but not too decisively because they had much bigger problems on their mind, like tracking down anticommunist underground Solidarity. Besides, like with many other controvercial things then, communists thought that allowing people to practice their strange hobby is a lesser evil than making them join an anticommunist organisation by bans.
