The word "where" requires a comma only where it introduces a non-restrictive independent clause. That is, where it presents additional information rather than identifying a specific thing or instance.
Examples:
"He went back to the house where he had left his keys."
(restrictive clause, identifies a specific house)
"He went back to the house, where he had left his keys."
(non-restrictive clause, the house is not modified)
"He visited the castle where the Blarney stone is displayed."
"He visited Blarney Castle, where the Blarney Stone is displayed."
"They crossed the border where it was unguarded."
"They crossed the border in the mountains, where it was unguarded."
