The Southern Netherlands is distinct for its Catholic culture in Limburg and North Brabant. Zeeland is also a part of it, and is mostly known for its historic efforts to tame the sea. The rolling landscape of South Limburg is a popular getaway for the locals.
The southern provinces have historically been the Roman Catholic area of the Netherlands, in contrast with Protestantism in the north of the country. That's still well visible in the architecture of churches and cathedrals, as well as in city centers. Nowadays, Catholicism is still the predominant religion in Limburg (where over 75% of people call themselves Catholic) and Brabant (just over half). It's said that the Catholic way of life brings a more bourgondic lifestyle to these provinces, especially in Limburg.
Try not to refer to the country as "Holland" here, as people from the south live in the Netherlands, and Holland is often a synonym for the more northern and western parts.
Take a look at the Delta Works, an engineering project that finally ended the Dutch' centuries' struggle against the sea. The most accessible storm surge barrier (with a visitor's centre) is the Oosterscheldekering at the Deltapark Neeltje Jans.
