Polish archaeologists digging an ancient latrine in the Baltic city of Gdańsk have stumbled upon a 250-year-old sex toy.

The phallic object is "large, thick, made of leather filled with bristles, and has a wooden tip," the Regional Office for the Protection of Monuments in Gdansk said in a press release.

Dating from the second half of the 1700s, the artificial penis was found "preserved in excellent condition."

According to the archaeologists, it was mistakenly dropped in the toilet by the person who was using it.

"It was certainly expensive. Cleaning revealed it was made of high quality leather," Marcin Tymiński at the Regional Office for the Protection of Monuments said in an interview with Radio Gdańsk.

"This is an extraordinary find for people researching the history of erotica," he added.

Other objects found in the latrine include fragments of pottery and jewellery. Several remains of wooden swords found nearby suggest the site was a fencing school.

The 18th-century sex toy has now been taken away for “maintenance,” the Regional Office for the Protection of Monuments said.
