The present Notre-Dame de Laon cathedral is the heir to an ancient building, built under the Carolingians and destroyed during the communal insurrection of 1112. Completed around 1235, the cathedral underwent a major restoration in the 19th century, and again in the 2000s. Note that since September 3, 2021, the building has been home to a “Blueberry of Memory” (a work of art by artist Matt Seaward) offered by the Bishop of Durham (UK) in memory of the soldiers who fell in the First World War.

Here, visitors will find an early masterpiece of Gothic architecture, a style often found in this part of France – Chartres and Reims, for example, attract enthusiastic international visitors and are far more famous than Laon. In the following 13th century, many Gothic churches were built, not only in their country of origin, France, but also beyond the country's borders, where this skyward-striving, light-filled architectural style was now in great demand for new churches (for example, the laying of the foundation stone for Cologne Cathedral in 1248).

The Porte d’Ardon is one of the medieval city gates of Laon. The current structure dates from the 13th and 14th centuries. Originally, this gate was called “Porte Royée” because of its proximity to the royal palace of Laon. The gate consists of a châtelet with a portcullis and used to have doors. There was also a barbican, but this has now disappeared. Under the gate there was a fountain and wash houses, some of which still exist. The Porte d’Ardon was classified as a historical monument in 1909.

The Porte de Soissons is a medieval city gate in Laon. It is one of the three remaining city gates of Laon and was built at the beginning of the 13th century when the fortifications were resumed. The gate is located in the south-west of the medieval city and is built of sandstone and limestone. The gate was originally known as the Porte Saint-Martin or Soibert, but was later renamed after the nearby town of Soissons. The rear of the gate (which was demolished in 1895) offers a cross-section of this type of defensive system: a vaulted room on the first floor, giving access to the harrow and the machicolation.

Loan is a medieval town on a mesa. A trip is very worthwhile! I would always prefer visiting Reims.
