Inside there are special breeding pots that are utilized in order to cultivate refined punga fruit. At the back of the church, are Woodrose and Nadine. Other tribals wander around inside as well, although they are of no significant mention.
The cathedral is named after the two English ships, The Ark and Maryland Dove, that originally colonized Maryland.
PlayStation 3Xbox 360 When you enter the cathedral and talk to Nadine immediately (and select all of the dialogue options), the cathedral may become locked. As there is no key, this is problematic.
Occasionally, the tribals will turn hostile towards you. When you attack them the whole Cathedral will turn hostile. Waiting 72–73 hours will take it until the tribals are calmed down and you can safely come back.
↑Fallout 3 Official Game Guide Game of the Year Edition p.673: "3.13: The Ark & Dove Cathedral (LAT 12/LONG 03) This cathedral, named after the two sailing ships landing in Maryland to establish the English colony in 1633, is now the main hideout for the Tribals, a cult group that believes in the power of the Punga plant. They are generally docile, unless their leader—Professor Calvert—orders them to attack. The cathedral grounds and gate are inaccessible until you've completed the Ritual of Mother Punga, during Main Quest: Walking with Spirits. Beware of Ghouls in the entrance area, which features a sealed gate and an intercom you can use to question Jimson. Don't forget the Ark & Dove Well [3.c] if you need a quick entrance down into the Sea Cave [U3.16], but only after you've opened it from the underground. Check to the right (southwest) of the main gate for a straw bed, Ammo, and Stimpaks on a tree stump.
