There is so much to see and learn in this castle with huge walls. Already, the Romans and Gallic tribes (mainly the Andecavi) had settlements at this place. The Romans called it Juliomagus .
The Counts of Anjou built a first stone fortification in the 9th century, which was expanded and beautified in the next centuries.
You should visit the former palace and large chapel first as there is an exhibition on the background of the large tapestry in the special building.
There is information on the apocalyptic times when the tapestry was made, how it was made, and much more.
The Tapestry of the Apocalypse is a masterpiece of medieval art woven from died wool with 25 different colours. Originally, it measured 140 x 6 meters, of which 103 meters survived and is on display. It tells the story of the   final book of the New Testament, the Revelations by Saint John.
The tapestry is divided into sections of 2x7 scenes with a larger image preceeding a section of a figure reading the Apocalypse. You follow the scenes in each section from top left to right and then from bottom left to right.
There are remarkable details in the scenes, so you take your time to appreciate it all.
Furthermore, there are some nice gardens on the walls where you can also have a panoramic view of the castle and the city
