Questions travellers ask

What is worth seeing in Poland?

This guide lists 10: Auschwitz concentration camp, Malbork Castle, Treblinka extermination camp and Centennial Hall (Wrocław) and others. Auschwitz concentration camp, Malbork Castle, Centennial Hall (Wrocław) and Białowieża Forest are UNESCO World Heritage Sites.

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 Poland 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.

Which places here are UNESCO World Heritage Sites?

4 of the 10 in this guide: Auschwitz concentration camp, Malbork Castle, Centennial Hall (Wrocław) and Białowieża Forest. That is not the full count for Poland, only the listed sites that made this guide.

What language is spoken in Poland, and what currency?

Polish. The currency is PLN.

How do I get mobile data in Poland?

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 Poland?

Play and Orange. 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 Play and Orange once you land, and installs by QR code before you leave.
