Our tour guide waited for a moment for Year End Party participants to enjoy king’s bathing pool, empress and their sons and daughters in the past. For a few minutes I imagined some possibilities of what the story would look like in this place on more than two centuries ago, definitely classics looked like colossal cinemas from old kingdoms. For a moment I thoughtfully enjoyed that imagination.
My focus was destroyed by tour guide’s call to continue journey into another part of Taman Sari. “We will see mosque, ladies and gentlemen!“, He said. I just followed with an ordinary feeling. I could only imagine an appearance of Great Mosque of Surakarta Palace, which I visited three months ago. “Oh, this mosque appearance will like that“, I closed my own guess.
For a moment I was in a large and neatly arranged courtyard with a visitor circular path which follow area shape. A magnificent ornate gate proudly stood at one side of this area, large and old trees covered participants from hot weather of Yogyakarta.


Meanwhile, on opposite side of it, there was a small gate with a door which leading visitors to underground. Ten minutes later, tour guide called group and they began to follow him into gate.
I was at back of them and began to descend stairs to follow the underground tunnel. “What kind of mosque is in underground?“, I kept curiously wondering.
“This mosque isn’t what you imagine, it is just a tunnel for worship. Because this mosque was hidden from Dutch colonialm. In ancient times, Dutch colonialism prohibited kingdom members from performing worship“, tour guide explained, which made me directly understood.


“It was only camouflage of a function as mosque. A brilliant idea from Sri Sultan Hamengkubuwono I, the first Sultan of Yogyakarta”, I started to admire this architecture in my mind. The tunnel could be passed without having to walk down your head, designed in such a way which it was sufficient for adults to pass through. During regular intervals, lamps were installed which would certainly helpful when the day turns dark. Tunnel walls were also shown original stone texture without paint, adding to its classic atmosphere.
I continued to explore along tunnel to find the end of this unique architectural masterpiece. I was even more amazed, the tunnel led to an arrangement of four staircases which were additional part of tunnels and also fifth staircase which was protruded from second floor tunnel to form a stage. “This stage was a pulpit for khateeb (Islam preacher) to give sermon, and palace’s family members would pray and sit listening to the sermon from the tunnel“, tour guide stood on pulpit while pointing his finger in several tunnels.



“Sermon sound would be heard until the end of tunnels because it used tunnel walls to echo the voice of khateeb” he continued.
Wow, I really praised the smart strategy of Sultan to be able to worship in the midst of colonial government’s prohibition. If Dutch colonial had inspected this place, of course, they would never have known if these tunnels actually functioned as a mosque of Yogyakarta Sultanate which was very secretive. They must have only suspected that this tunnels only served as an access between sides in Taman Sari area.
This mosque was nicknamed as SUMUR GUMULING.
