The roof is actually a dull shade of yellow, but looks otherwise if you are lucky to visit it when the sun shines on it. Which is very rare, as this little building is surrounded by other bigger buildings.
The museum was closed when we visited so I can't say if it is worth going inside. But it is easy to imagine royalty up there looking down at the little square :-)
There are combo tickets for the tower and the roof at 7 euros if not using an Innsbruck card.
