One of the most important reminders is that we recommend that you do not lean on the iron fences inside the Basilica. Because iron fences are slippery. A short note to avoid encountering unexpected issues.
Basilica is a one-way, narrow corridor destination. During the walk, it may suddenly get dark between light shows. We recommend that you use your phone's flash light during this period.
You can take photos however you want without hesitation.
