St Peter's Seminary sits in woodland about an hour west of Glasgow, near a village called Cardross. If you like Brutalist architecture, then it's a beautiful ruin: if not, then perhaps your view isn't so kind. It's a historic, religious building: but it's also a money sink that can't be demolished.

On Nantasket Beach in the seaside town of Hull, Massachusetts, sits the last play-for-cash Fascination Parlor in the world. It's a century-old arcade game, made of relays that click and buzz. There are a few other parlors left in the world: but this is the only one where you're playing for actual money.

Gibbs Farm, in New Zealand, is an enormous private sculpture collection. Its most famous piece is Horizons, by Neil Dawson - and it looks like a cartoon tissue somehow painted onto the landscape. To see it in person, though, will take a bit of effort.

The Ports of Auckland are automating their straddle carriers, which might not seem like much: until you phrase it as "hundred-tonne autonomous robots guided by nanosecond-precision tracking".

Mount Taranaki, on the North Island of New Zealand, is a large-scale circle that's visible from space: a stratovolcano with six miles of forest around it. But that didn't happen naturally. Oh, and there's a good chance that, in the next fifty years or so, it might explode.

Near Hindon, on the South Island of New Zealand, there's one of only two remaining one-lane road-rail bridges in the country. No barriers, no lights, no sirens: if you're driving across this, you need to make sure to listen out for the train horn.

The Byron Bay Railroad Company runs the world's first 100% solar-powered train. It wouldn't work everywhere - but in the bright sunshine of Australia, it might just be the right tool for the job.

If you believe the hype, then the Metropolitan Area Underground Discharge Channel stops Tokyo flooding. It doesn't. But it is one colossal part of a huge network of flood defences that protect a city that would otherwise be... well, very wet.

On a coastline that's steadily sinking under the waves, the Wax Lake Delta is rising: which is a wonderful thing for researchers.Historically, every time humans try and mess with the Mississippi, there have been unintended consequences: and even though we can now model it fairly well, there are still surprises.

The Berkeley Pit, in Butte, Montana, was once the richest hill on Earth: the Anaconda Copper Mine. Now: it's not all that rich, and it's not much of a hill. Instead, it's a toxic pit filled with sulfuric acid.

Onkalo, on the Finnish island of Olkiluoto, is planned to be the first geologic storage facility for high-level nuclear waste: eventually sealed for 100,000 years. I got to see inside.

Next to Amsterdam Schiphol Airport is the Buitenschot Land Art Park, a giant set of ridges and furrows cut into the landscape. Yes, it's art: but it also stops some local residents from being exposed to jet noise.

In Stockholm, there's a diagonal wind tunnel, used for one very specific purpose: learning to fly a wingsuit. I tried. I almost managed it.

In Wichita Falls, Texas, the Newby-McMahon Building stands 480 inches tall. Not 480 feet: 480 inches. There's a story of a smooth-talking scammer that sounds almost too good to be true. But is it?
