What is the main setting in the novel, Molloy?

Referred to as "Molloy's country" by Moran, Ballyba is a fictional town presumably in Ireland that Moran journeys to in order to find Molloy. Ballyba is described as a grey marshland, with small copses, a “strangled creek, which the slow grey tides emptied and filled” (129). Moran describes it as a barren land that cannot be cultivated, so its residents craft knickknacks from bogwood and weeds.
