Within the forest of bounded by Tyersall Ave and Holland/Napier
Road, lies a big mansion that had seen better days.
Many blogs and photo albums have been written about this
mansion.
This mansion was also covered by Shin Min on 5 Dec 07.

Translation:
Beside Botanical Gardens, there is a empty abandoned piece of land
with a old mansion built by a Johor Sultan.
This empty mansion has been abandoned for 50 - 60 years, but last
Jul 10, there was a mysterious fire that nearly burned the whole
mansion down. THe roof also collapsed.
It is also mysterious that this mansion has caught fire 2 other
times, and once 700 people were killed.
According to some people with 3rd eye, the souls of those 700
people would still be seen even now in the mansion.
According to one local paranormal group with such a third eye,
besides these 700 spirits, this quiet mansion would also be the
occasion of some "festive" atmosphere. When this member was there,
he used to saw imperial guards stationed outside the house, and
inside the big hall, there were well dressed royalty, high society
ladies and gentlemen and businessman attending a party there.
Not so long ago, he also came across a man styled and dressed like
an English gentleman sitting leisurely on an old sofa.
This reporter follow this parnormal group member to the mansion,
which is a certain distance from the busy Holland road. It was
surrounded by wild grass and bushes.
The whole mansion was blackened and there was no rooftop. It was
severely damaged. But from the building plan, one could still see
the former storage room, laundry room and bedrooms etc.
However the reporter could not see any 700 spirits, nor royal feast
nor guards nor English gentleman, but some mysterious footprints on
the walls and ceiling. These footprints looked like those of cat's
paws prints.
The reporter is puzzled how come the cat paw prints appeared on the
celing? From the size of the prints, it does not look like that of
a lizard.
The Two Fires
This old mansion was built by Sultan Abu Bakar in 1890. In 1905 Sep
10, this mansion caught fire was was badly burnt. It was then
rebuilt in 1932. In 1942, this mansion was temporarily used as a
hospital for the soldiers fighting in Singapore.
In Feb that year, Japan invade Singapore and this hospital became a
military target. Again a fire occured and 700 medical workers and
soldiers were burnt to dead, non survived.
