Travel photo porn is one of our favourite bits about telling travel stories. And it’s time again to get out the travel snaps and explain the quirky adventures behind them, in the latest edition of Slide Night.

Back in a Bit regular Jean McBain discovered an assuming church in Krakow, Poland, where behind a brick exterior lies intricate wall paintings and stained-glass windows…

Jean McBain writes: Krakow in Poland was the source of many interesting experiences, friendly encounters with fellow tourists, and beer-induced headaches for us. In Poland’s old capital we visited the mind-blowing Wieliczka Salt Mine, which was mined for 900 years, closing only very recently.

It was in Krakow that I discovered one of my favourite souvenirs, a library card for the Jagiellonian Library which was founded in the 14th century. And it was also in Krakow that we found one of the most beautiful churches in Europe.

The Franciscan order established a branch in Krakow in the 13th century. Time passed, they built a church to service the monastery, and then in 1850 disaster struck.

A fire destroyed much of Krakow’s old town and gutted the Franciscan Church. After the exterior was patched up the monks took the courageous decision to employ a young artist called Stanislaw Wyspianski to design the interior. The result is an Art-Nouveau fantasy, with a swirl of murals in a mix of natural and geometric patterns. The masterpieces are the stained-glass windows. Above the western entrance is a huge window depicting God in the process of creating the universe, although the imposing figure made me think of Gandalf from Lord of the Rings.

You can find this unassuming-looking church at: Plac Wszystkich Swietych 1, Krakow, Poland
