The accordion museum has been moved to the Tourist information center in this location (from my understanding the original location was the location, from which the owner ran the museum, which has now been given to the city of Litovel, hence the movement). Current location of the node is here: Node: Muzeum harmonik (3656886444). Opening hours, exact address can be found here: https://www.muzeumharmonik.cz/.

In the Transport map the denotation of the Jiráskovo náměstí stop area is not connected (between the C and D sections).
