Questions travellers ask

What is worth seeing in Luxembourg?

This guide lists 10: Kneiff, Berg Castle, Notre-Dame Cathedral, Luxembourg and Grand Ducal Palace, Luxembourg and others.

How were these places chosen?

By machine, from open data, with no human ranking them and nobody able to pay for a place on the list. Everything Wikidata records in Luxembourg that is a building, a landform, a protected area or a tourist attraction, has coordinates, a photograph and an English Wikipedia article, is ranked by how many Wikipedia language editions wrote about it. Provinces, cities, airports, stations and stretches of sea shared with the neighbours are filtered out.

What language is spoken in Luxembourg, and what currency?

French, German, Luxembourgish. The currency is EUR.

How do I get mobile data in Luxembourg?

A travel eSIM is usually the cheapest way, and avoids a roaming bill. The plans suggested at the foot of this guide start at $1.81 for 2GB per day. The eSIM is data-only and sits alongside your normal SIM, so calls, texts and WhatsApp keep working on your own number.

Which networks would my phone use in Luxembourg?

Tango, Orange and POST. Your phone picks whichever has the best signal where you are, the same way a local phone does.

One practical note: staying online

Maps, tickets and translation all want data, and roaming is the expensive way to get it. A Computatus eSIM eSIM connects to Tango, Orange and POST once you land, and installs by QR code before you leave.
