Question: In how many places can I find people who were the architects of the Dundas Castle?
SPARQL query:
PREFIX res: <http://dbpedia.org/resource/>
PREFIX prop: <http://dbpedia.org/property/>
SELECT DISTINCT COUNT(?uri) WHERE { <http://dbpedia.org/resource/Dundas_Castle_(Roscoe,_New_York)> prop:architecture ?x . ?x prop:region ?uri . }
