The lines were so long to get into this Cathedral that I almost decided not to visit it. I am glad that the line was very short on my last afternoon in Seville or I would have missed it’s beauty and the sound of its huge organ (not to mention the tomb of Christopher Columbus).
I just happened to tour the Cathedral while a service was going on. The sound of the organ was incredible.
There was a small museum area inside near the entrance with many small exhibits.
One of the many special exhibits.
There were many beautiful chapels and a lot of them housed tombs.
Edit
The above chapel from another angle. 
Another beautiful chapel with covered pews. It looks like it gets used for special events. 
The sculpture of the severed head of John the Baptist is in the museum. I saw one just like it in the Cathedral in Granada. Seems a little gory.
Again….WOW!!!!
Some chapels were less ornate which was less overwhelming allowing for a deeper appreciation of the art work.
The paintings in some of the chapels were beautiful. They were mostly in the less ornate chapels.
Beautiful.
There was a mirror strategically place to allow you to take a picture of the ceilings high above your head without breaking your neck to get the right angle.
This was painted directly on the wall and is huge. It is right beside the tomb of Christopher Columbus.
It was hard to get a good angle to capture the life-size sculptures high up on the gate.
The details are unbelievable especially considering how long ago this Cathedral was built. It was started in 1402 and originally completed in 1511. Since then the dome has collapsed and been rebuilt twice.
The Chapel of the Virgin Mary.
Chapel pictures are mostly taken through the protecting bars however many of the chapels in this Cathedral were open to the public.
The central nave of the Cathedral rises 42 meters and the center of the nave houses the large choir box seen on the right of this picture along with the huge, ornate organ.
An alter open to the public.
Another angle.
A large wooden sculpture in the central courtyard of the Cathedral.
There were so many beautiful chapels I couldn’t stop taking pictures . … there isn’t room for all of them in this post so I will leave you with this last picture .
