It was worth a visit about thirty minutes from the pier. It was Sunday and there was activity inside so we couldn't get in, but we stood in the porch area and listened to the wonderful sound of singing and organ for a few minutes. The church reopened after the boat had left, and we were content to stop just in front of the magnificent door - reminiscent of Notre Dame. We also went to the Bishop's Palace Gardens for a stroll. There was also a museum and cafe, but we didn't have time to visit. A walk to the cathedral is worth it.
