The logistics of trying to see everything can be a challenge, especially in a location is complicated opening times. Fortunately Mainz is both highly interactive and tourist friendly. Below I have summarized the opening hours for each of the accessible destinations in my guide.
|Landesmuseum /Mainz State Museum||Tuesday-Sunday 10am-5pm|
|Gutenberg Museum||Tuesday-Sunday 9am-5pm|
|Mainz Cathedral||Mon-Sat 11am-4pm / Sun 1pm-4pm|
|Mainz Cathedral Treasury||Tue-Thu 1pm-5pm / Fri-Sun 11am-6pm|
|Augustine Church||Monday-Saturday 8am-5pm|
|St. Peter||Everyday 9am-5pm|
|St. Ignaz||Everyday 9:30am-7pm|
|Carmelite Church||Monday-Saturday 7am-7:30pm|
|St. Stephan||Thursday-Sunday 12pm-4pm|
|St. John||By Appointment Only|
|Electoral Palace / Roman Museum||Closed Indefinitely for Renovations|
For Mainz the best times appear to be Thursday-Saturday, and I don’t see the need for any special considerations given the standard times.
