Fans who can't wait until Sunday for the third season premiere of "Downton Abbey" can visit the abbey itself on "Castles on Camera: Royal Residences on TV" (9 p.m., HGTV).
The abbey is really Highclere Castle, home of the Carnarvon family since 1679. Other venerable domiciles featured here include Althorp, home of the Spencer family and where the late Princess Diana is buried.
"Castles" visits Cliveden House in the English countryside, built in 1666. In the first half of the 20th century it was the home of the Astors, who
Cliveden House gained a notorious reputation in the late 1930s as a gathering place for British aristocrats eager to
appease Adolf Hitler and even bring his Nazi policies to Britain. They were known as the Cliveden Set. These sensibil-
ities were touched upon on the recent incarnation of "Up stairs Downstairs" on PBS. There's no telling if "Downton Abbey" will stick around long enough to get us to the late 1930s.
---"Portlandia" (10 p.m., IFC, TV-14) enters a third season with a witty meditation on the desire for (and the lack of) social and cultural outrage.
After buying a TV at a thrift store -- his first in decades -- the over-pierced bike messenger Spyke (Fred Armisen) is shocked to discover that MTV has become home to nothing but shows about pregnant teens and kids arriving at red carpet functions in limousines. He becomes obsessed with occupying MTV and bringing back the "Rock the Vote" era. Former MTV newscasters Kurt Loder and Tabitha Soren appear as themselves.
Look for Roseanne Barr, Rose Byrne, Bill Hader, Juliette Lewis, Bobby Moynihan, Martina Navratilova and Patton Oswalt to guest star on "Portlandia" this season.
