Hi EBattman, and thanks for the reply.

tourism=* is certainly the way to go for this tower. I've added tags for two tourist features, since they're slightly different in nature, and different features in OSM should get distinct objects

1. the viewing platform: https://www.openstreetmap.org/node/12819165592

2. the historic building itself: https://www.openstreetmap.org/way/311139684

Don't rely on the node/way IDs too much, since they might be replaced with new objects. If you're freshly pulling tourism=* on a reasonable regular basis though, you're good to go, no matter how we divide up the map features
