Planning a trip can be time consuming even in our internet age if you need to look at each point of interest via their individual website.
Heading for Paris and hungry for a cultural fill, you will find all 14 City of Paris museums under one roof, Paris Musees....
History buffs will want to check The Catacombs while literary minded can delve into Balzac's House, and classical music fans could check cast of Chopin's hand at Museum of Romantics which is currently under renovation and offers free access to permanent collection (only partly accessible because of renovations).
Paris Musees web portal landed on my radar thanks to Elodie's Paris
