After yesterday’s knowledge day, we had an activity day today. We started with a team treasure hunt, with very varied tasks – obscure facts about Slovenia, themed photo challenges (a photo of a license plate with “13” in it; a photo of a stranger wearing something 13|37-branded) and teamed photo challenges (at least 8 people of the team jumping and actually in the air at the same time), visiting odd spots of the city and solving maths puzzles.

I was all peopled out after yesterday so I went off on my own and bagged a few of the far-off walking challenges for our team. It was rainy and sweaty. Especially walking up the castle hill afterwards to rejoin my team. I barely took any photos, both because the rain made it difficult and because I had a tight deadline to meet.

For the afternoon we had a choice between a city tour, a boat tour on the river (which was cancelled for safety reasons due to the rain and flooding), a culinary tour (which I assumed would involve lots of meat and wine) and a hike. Even though we spent a full day walking around Ljubljana just a month ago, I guessed that the city tour would show me new sides of the city, so that’s what I went for.

Our group had barely left the castle when our guide showed us the first hidden detail. Ljubljana was built near the site of an abandoned Roman settlement, and they reused chunks of the old ruins to build the castle. A stone is a stone!

Having walked down to the bottom of the castle hill, the guide took us on a tour of the air raid shelters under the hill. Fully maintained still, and ready to be used at 24 hours’ notice, he told us – and actually used for real during the Ten-Day War with Yugoslavia in 1991.

Along one of the main shopping streets, our guide showed us the narrow ventilation corridors between the medieval houses. The buildings all back up onto the hill, and the corridors help air out the moisture. Most of them were either bricked up or shut behind gates, but at least one was open. The far end was narrow enough that I could barely turn around.

The guide also pointed out that all the medieval houses are exactly three windows wide. Apparently this was a rule in medieval times. I walked down this street last time I was here, and paid attention to the views, but never noticed this detail – nor the ventilation corridors.

The river, when we passed it, was seriously flooded and I totally understand why the boat tour had to be cancelled.

This lovely little street with all its greenery and flowers was as beautiful today as it was in August.

Naturally Ljubljana’s city architect Jože Plečnik was a recurring topic during our tour. I learned, among other things, that he was heavily inspired by classical Roman and Greek architecture and really, really loved pillars. An ongoing joke during our tour was that if you see any pillars anywhere, then Plečnik was probably the one who put them there. And indeed we saw pillars in the oddest of places – such as “on the outside of a wall, three meters above ground”. Go figure.

The grounds of the Ljubljana Festival, inhabiting what used to be a monastery, were my favourite place in the city. The juxtaposition of baroque statues of saints with Soviet imagery of red five-pointed stars, hammers and pickaxes, is pretty unique.

Towards the end of our tour the rain had more or less let up. I had come prepared for a lot more rain than we actually got (a pair of rubber boots took up a quarter of the space in my baggage) so I was dry and toasty all the way. But drier weather made photography easier.

We capped off the day with a gala dinner in the hotel’s grand hall. More festive and glamorous than most events in the software industry! I quite enjoyed dressing up for once.
