Our trip to Czechia concluded with a road trip to the Kašperk and Rabí castles. Both are medieval castles, partially in ruins and partially restored. Kašperk's two-towers-on-a-steep-hill design reminded us very much of the Trosky castle that we had seen a few days earlier.

Otok Vrnik is a small island close to Korcula (town) and the Korcula island. Otok Vrnik's history revolves around quarries ... the whole island is a quarry. Since the activity has stopped hundreds of years ago, there's little that you can see today, but there are some places where big walls of rock are still visible.

60 kilometers southwest of Prague is a historic mining area of Příbram. There's mining museum at Mine Ševčinský. There's also two mines that you can actually visit, the Hornické muzeum Příbram – Vojtěšský důl (Vojtěšský mine) and the Hornické muzeum Příbram – Anenský důl (Anna Mine). The latter involves a small train journey in mine carts...

The Sutro Baths were luxurious swimming pools on the San Francisco seafront, in an almost all glass building, built in the 1890s. Complete with salt and freshwater pools, slides, and 30 swinging rings, and a springboard. It was served by two rail lines, one of these being the Sutro Railroad, another creation of Adolph Sutro, a famous engineer and industrialist and mayor of San Francisco! In the 1900s the facility fell into disrepair and it burned down in 1966. Today only ruins remain, including the pool basins, a settling pool, and tunnels.

Croatian islands have had a military past. During World War II when Tito held his headquarters on the island of Vis. After the war, Vis was turned into a defense bastion, and only opened for foreigners as late as in 1989. Today we toured a maze of tunnels on the Zagrebenje mountains on the southeast corner of the island, connecting a number gun positions.

Coming back from the skiing on the Mount Olympus and Troodos Mountains in Cyprus, I was driving by an area that had reported some kind of underground passage. I stopped to find out what it was about. From the map it looked like it was near a road, but it turned out to be only near some kind of agricultural path, and a kilometer or two from the drivable public roads. Well, why not walk to the darkness on the first night in a country you've never been to...

Großer Bunkerberg is the name of the Berlin ruble mountain in Volkspark Friedrichshain. It housed previously one of Berlin's air defense 'flak towers', the Flakturm II G. Only a small corner of the blown up tower is still visible on the site, at the top of a large hill.

Zmajeva Pećina, "Dragon's Cave" is a small hermitage on the south shores of the Brač island in Croatia. The cave is only 20 meters long, but is a fascinating visit, both because is such as fascinating view, high cave on a high hill, and also because my guide Zoran knows so much about the history of the place. This is a cave that houses a monastery. Or housed, it is in ruins. Very interesting!

The evening's excursion was to Lohja's Karstu area, in search of caves. The Linnanmäki is a high hill and cliff in Karstu, and the book Suomen Luolat notes that there are two caves on the hill. One was supposed to be inaccessible without climbing equipment. But as usual, the coordinates were inaccurate, so I ended up going around the entire hill, and I think found the other cave plus four other small roof/shelter caves.

Korpikylä ("Remote Village") is a region in Hyrylä. I was stopping in Hyrylä for other reasons, and looked on the map for an interesting place to go snowshoeing in. Korpikylä fit the bill, and after some searching for a parking place I headed out for a two-hour nice hike in snowy forest.

I continued my earlier underground tests with iPhone 12 Pro's LiDAR sensor and software. This time I started testing the 3D modelling software. Can we produce an accurate 3D model of a cave using these sensors and software?

We drove in two cars to south end of the Porkkala peninsula -- 50 minutes away -- to explore three bunkers there. The best map that we have of the abandoned Soviet-era bunkers comes from Lynx, the local orienteering club. Unfortunately, this time their map oversold what was to be found at the location.

Need some excitement? Maybe crawling inside a blown-up bunker in the middle of dark forest would help. Hope the Nazi command is no longer on site... and that the ammunition laying in the ground isn't dangerous.

Today's swim was at the lake Tampaja, which I had never heard about before. It is a medium-sized lake near Lapinkylä in northern parts of Kirkkonummi. There's a nice public beach, but unfortunately not much space around for a more socially distanced swims.

I was looking for a place to swim in Sundberg, Kirkkonummi. My first attempt was to get to the apparent harbour on the west side, near Morbacka. Could it be a Soviet-occupation era harbour? And maybe a swimming would also be possible? This needed investigation.
