A military museum has asked its visitors to stop having sex at the historic site.

This request was made by the military museum after security cameras caught several โ€˜lustyโ€™ couples in the act.

The Fort Gerhard museum said that they saw โ€œthree lovers engaged in trystsโ€ in the span of just one month.

Fort Gerhard museum is a former 19th-century Prussian fortress in the coastal town of ?winouj?cie in Poland.

โ€œOur guests are kindly requestedโ€ฆ how can we put itโ€ฆ no ars amandi [the art of love] in the museum, please!โ€ Fort Gerhard museum stated in its social media pages.

It added: โ€œWe ask our amorous guests to be understanding โ€“ most of the exhibits in our museum are from many years ago and accustomed to entirely different moral norms โ€“ conservative, even orthodox and abstemious. Let’s not expose them to discomfort!โ€

According to the museum’s website, its exhibits ranges from โ€œthe times of Frederick the Great to the end of the Cold Warโ€.

Museum director Piotr Piwowarczyk told local newspaper Gazeta Wyborcza: โ€œIn less than a month we have already had three recordings of lovers engaged in trysts.โ€

โ€œVisitors to the fort have various temperaments, some of them very conservative. We don’t want them to be shocked during their visit by stumbling across a couple engaged in lustful antics,โ€ he added.

Notably, sex in public is illegal in Poland inviting detention, a non-custodial sentence or a fine of 1,500 zloty (about ยฃ250).
