After moving to Luxembourg, I decided to write some code to scrape the addresses of all post boxes in the city from this website and put them into Google Maps, allowing me to find the nearest post box as well as learning a bit about pulling data from websites. For some reason, such a map was not available from the post office, and the website itself didn’t help. It gives the addresses of the post boxes sorted alphabetically, which in itself is not as helpful as a map. Since the local address convention is to put street number before street name, the addresses are sorted by street number, which is even less helpful.
After sharing the map, a helpful reddit user showed me that a datafile containing all the addresses is also available at data.public.lu, where a bunch of different publically available data from Luxembourg can be found.
