The original appearance of Gangnyeongjeon in Gyeongbokgung Palace
The roof catenary line is fairly straight.
Because it is a horizontally long building, it seems to have been intentionally made close to a straight line.
The visual sense of left and right balance is because the high points of the descending ridges at both ends are very high.
It complements itself without having to make the catenary line round.
The horizontality of the top and bottom is emphasized, giving a very grand and massive feeling.

There is also a video record of the restoration process in which Chief Pastor Shin Eung-su participated on YouTube.
Does Daemokjang reflect his own aesthetic sense, unrelated to the original work?
Or, I don't know if they did it mechanically, thinking, 'Because it's a hanok, I need to add curves.'
The catenary curve is made much deeper than the original.
Looks sleeker than the original
Originally, the catenary line of Gyotaejeondo was almost straight.
Only the tip is slightly raised
During the new restoration, the roof line was rounded.
'Isn't it so much that you can't feel any difference?'
You may have doubts, but
Let's see what results this subtle difference produces.

Looking from the front
It looks like something was pressing down on the building from above.
The curvature is so severe that the center becomes thin and only the left and right sides are raised, breaking the balance.
When looking at the eaves of Hyanggomun, the main gate of Gangnyeongjeon, there is no camera distortion.
The actual roof line was restored incorrectly,
This is what it looks like when you see it with your own eyes from Gyeongbokgung Palace.
The reason for adding a suspension curve in the first place is to pursue visual balance.
If the balance is visually broken
it is a failed work
In particular, horizontally long buildings need to be very careful about using curves.
It's not for nothing that our ancestors built the roof lines of Gangnyeongjeon and Gyotaejeon in a straight line.
Even if the angle is off by just 1 degree, your balance will be broken.
It must be made under very detailed calculations.

So now you have to watch it again
Huijeongdang and Daejojeon Temple in Changdeokgung Palace
The reason I came to Changdeokgung Palace while talking about Gyeongbokgung Palace is,
This is because these buildings are the originals of Gangnyeongjeon and Gyotaejeon, respectively, built during the Joseon Dynasty.
Around the early 1900s, there was a fire in the inner palace of Cheongdeokgung Palace.
At that time, Gangnyeongjeon and Gyotaejeon in Gyeongbokgung Palace were torn down and Huijeongdang and Daejojeon were built.

Like the original, the roof line is very straight and stable even when viewed from the front.
Now again
Let’s compare it with the currently restored Gyotaejeon.
Shaped in the middle
Now let’s look at the roofs of other ‘horizontal buildings’.

stability there is form
also horizontally long It's a building because
catenary line steeply Don't put it in Without
in a straight line On the way Only the end a little Sincerely
If we go even more extreme, it is the Jeongjeon of Jongmyo Shrine.
It is also a straight line and is slightly raised only at the left and right ends.
Good linear balance
What if a long rope over 100 meters long was stretched to the main shrine of Jongmyo Shrine and a suspension curve was created like a saggy line?
The result would have been so terrible that you wouldn't even want to imagine it.
So, is it okay to put catenary lines in a round shape for buildings that are horizontally short?
Of course not

(I can't find a large photo.)
If you look closely at the ridge,
The middle is straight and only the left and right ends rise.
I even put a stinky bean on the end of the ridge.
It is presumed that the ridge was made gently in consideration of the presence of the tall ridge.

It looks like it has gone through some repair work.
The ridge has changed
The curve of the roof is so steep that it looks like someone pressed it down with a fist.
Plus, the odor is soaring that my balance is getting weird.
The location of the schnitzel is also a little more inward than it should be, which makes it even more strange.
(Currently, Bongeunsa Temple is excessively praying.
A completely different building has been built, and the whereabouts of the Four Heavenly Kings Gate are unknown.)
Just make it the way it was originally made.
Why do carpenters have such strange tastes?
An aesthetic connoisseur developed by carpenters during the Joseon Dynasty through the accumulation of hundreds of years of architectural history.
The size, shape, height, decoration, and even the background of the building.
Considering various aspects
The optimal catenary line was selected.
In modern times, if we unconditionally make Hanok curved without thinking about the reason,
Of course, something ugly is bound to be born.
