The Romanian salt mine Salina Turda can trace its origins back several centuries, having first begun operations in the 17th century. It was even used as recently as 1932, until its closure that year, and it has since remained abandoned.
That was until recently, as a new tourist destination has been opened in the heart of the old salt mine, with all the number of cool attractions. A museum and walking tours are available, and there is even a large space to hold special events. Visitors can also enjoy fun games and activities such as pool and table tennis, and you can even hire a bot and go for a leisurely paddle in the underground lake found in the mines.
