HP and the Pillar of Storge- Philisophical or Real?

For those who don't know there is a strong rumor going around that the
name of the next book is 'Harry Potter and the Pillar of Storgé'. 

This has been posted on Mugglenet and at The Leaky Cauldron, it's
something someone claims to have discovered on JKR official website,
although it appears that it wasn't suppose to become public knowledge
until the first of July.

For those who are not following along, 'Storge' is one of the four
philisophical concepts of love-

Storge - love & loyalty within families
Philia - love & friendship between non-related people
Eros - romantic, erotic love
Agape - divine love

In concept the 'pillar' or strength of family love is great, but the
previous titles have all referred to REAL objects, ...well, real in books.

"Harry Potter and...
... the Philosophers Stone" (an actual stone)
... the Chamber of Secrets" (a real chamber in the castle)
... the Prisoner of Azkaban" (a real escaped prisoner)
... the Goblet of Fire" (a real cup related to the Tri-Wizards Tournement)
... the Order of the Phoenix" (a real organized group of people)

and now...

... the Pillar of Storge"  [although not officially confirmed yet]

Questions-
-Does anyone know of any real world monuments to the four concepts of
philisophical love? Are they by any chance 'pillars' or stone columns?

-I can very easly see the 'Pillar of Storge' as a concept that applies
to the books and fits nicely into the story line. Family love could be
and is a very deep and complex theme in the books already. 

The problem I have is with the assumption that the book titles will be
consistent all the way through the series, which implies that the
'Pillar of Storge' is a real object. So... what could it be and why
does it exist?

...a monument to love?

...a special magical object? 

...a monument to Phillip Storge, the inventor of the Self-Weeding
Garden Charm? (I made that up, but I think you get the point)

I remember may speculation about what the 'Goblet of Fire' was, and it
would be nice to go back an look them up, if only they weren't buried
under 50,000 posts. I remember many of my own deep and well thought
out speculations that I was convinced were right; which, of course,
were hopelessly wrong. 

I guess my point is that I have no problem with the philisophical
concept of 'Pillar of Storge', but I'm at a loss for a way to turn it
into a real physical or magical object, or place.

Just a thought.
