The House of Tales is a lovely place in the heart of medieval Paris, Le Marais. It's where children come to hear stories, tales, fables and legends of oral tradition. There's also a large library with books from all countries such as Africa, the Caribbean and China. You sit to read and have coffee or tea, the walls have works of modern artists, generally illustrating stories, and you can buy the pictures and some books. They also have crafts workshops for children.
I loved visiting the Dalí Area in Paris. I'd been many times to Montmartre but never to the space dedicated to this controversial artist. I admit that I love or hate his works in equal parts. I just happened upon this small museum that was hidden and I really liked it. The exhibition is devoted almost entirely to his most famous sculptures. A BLAST! Don't miss this corner of Spanish art in a neighborhood that has been dedicated for years to artists and recent art history. The price was about 10 euros.
When walking through Saint Germain neighborhood I recommend a short detour to Verneuil Street. Go to the house of Serge Gainsbourg, in which the words of the great classics were written, but unfortunately are partly covered with graffiti, though this does not detract from the symbolism of the place.
Misstic, is a series of murals that adorn the streets of the thirteenth arrondissement of Paris, in particular in the area of Butte aux Cailles. They are funny, spiritual and often political messages that are a reminder that this part of Paris remains connected to its roots, for example to the mid-nineteenth century workers. To me, they make this place charming.
