Place Guillaume II - Knuedler

A festive heart of Luxembourg during the Christmas season! I visited William Square during the Christmas market, and the atmosphere was absolutely magical. The square transforms into a cozy winter wonderland with charming stalls offering affordable mulled wine, popcorn, and Luxembourg-themed souvenirs — perfect for gift shopping or just enjoying the holiday vibes. The city organizes everything beautifully: heated areas, pop-up bars, and festive decorations create a warm and welcoming space to celebrate the season. It’s not just a market — it feels like the whole city gathers here to slow down and enjoy.

Great place for tourists to hang around & enjoy Luxembourg one of the richest countries in the world. Quite, laid back, good views in walking distance & what a history it has

Very clean and bougie square. Good parking underneath the square and big enough for a full size european SUV like and X5 or similar vehicle up to 2m tall. Very safe area, close to many good food places, Notre Dame and other sites. Worth seeing once if you get a chance.

This public Square has been around since the 13th century and it's named for The Dutch king William II, who was also the Grand Duke of Luxembourg at the time. Although not the most popular square with tourists, there are several landmarks including the town hall and an equestrian statue of the eponymous king.

It is a nice pretty square in the heart of Luxembourg City but is hardly any different from most other European town squares in essence. Make a beeline for this place while coming from the Notre Dame cathedral to cover the sights and sounds of Luxembourg City.

The Mäertchen is a cherished traditional market held annually in Luxembourg City, closely tied to the religious observance known as the Octave of Our Lady of Luxembourg. This event honors the Virgin Mary, the patron saint of both the Grand Duchy and its capital.  ⸻ 📜 Historical Background The origins of the Mäertchen date back to the 17th century during the Octave pilgrimage, which began in 1666 amid a devastating plague. Believers sought solace and healing by venerating a wooden statue of the Virgin Mary, believed to possess miraculous powers. Over time, this pilgrimage evolved into a significant religious tradition, attracting pilgrims from across the country and the Greater Region to Luxembourg City.

Was very quiet when I visited not many people around, but then again it was about 10 o’clock in the morning. He got busier around lunchtime so some great architecture and I managed to get Small photos of the area.
