Problem: Slavs:

Around the 6th century, Slavs appeared on Byzantine borders in great numbers.[page needed] The Byzantine records note that grass would not regrow in places where the Slavs had marched through, so great were their numbers. After a military movement even the Peloponnese and Asia Minor were reported to have Slavic settlements. This southern movement has traditionally been seen as an invasive expansion. By the end of the 6th century, Slavs had settled the Eastern Alps regions.

Where had the Slavs settled by the end of the 6th century?
---
A: the Eastern Alps

Context and question: The pagan Slavic populations were Christianized between the 6th and 10th centuries. Orthodox Christianity is predominant in the East and South Slavs, while Roman Catholicism is predominant in West Slavs and the western South Slavs. The religious borders are largely comparable to the EastWest Schism which began in the 11th century. The majority of contemporary Slavic populations who profess a religion are Orthodox, followed by Catholic, while a small minority are Protestant. There are minor Slavic Muslim groups. Religious delineations by nationality can be very sharp; usually in the Slavic ethnic groups the vast majority of religious people share the same religion. Some Slavs are atheist or agnostic: only 19% of Czechs professed belief in god/s in the 2005 Eurobarometer survey.
When did Slavic populations become more atheistic?
Answer: unanswerable

Question: Until the Church Building Act of 1818, the period saw relatively few churches built in Britain, which was already well-supplied, although in the later years of the period the demand for Non-conformist and Roman Catholic places of worship greatly increased. Anglican churches that were built were designed internally to allow maximum audibility, and visibility, for preaching, so the main nave was generally wider and shorter than in medieval plans, and often there were no side-aisles. Galleries were common in new churches. Especially in country parishes, the external appearance generally retained the familiar signifiers of a Gothic church, with a tower or spire, a large west front with one or more doors, and very large windows along the nave, but all with any ornament drawn from the classical vocabulary. Where funds permitted, a classical temple portico with columns and a pediment might be used at the west front. Decoration inside was very limited, but churches filled up with monuments to the prosperous.
Is there an answer to this question: What were filled with monuments to God?
