Or the ministry of Time. Not sure why I started watching this, but delighted that I did.

A spanish ministry established centuries ago when it was found that alternate times can be travelled to through a series of doors. Each door leads to a different time and place.

The ministries aim is to ensure that Spanish history is not tampered with by outside influences using alternate doors for their own nefarious means.

Just finished the first (of three) series and thoroughly enjoyed it (even though I know little about spanish history). Would work well in pretty much any country (well maybe not America).
