An obelisk is a tall, thin, four-sided, tapering monument which ends in a pyramidal top.
An obelisk (known as a Bantaca spire) was located in the center of the Bajoran city of B'hala. It was included in an icon painting of the city. In 2373, Captain Benjamin Sisko was able to recreate the obelisk in one of Quark's holosuites. Using the holoprogram, Sisko was able to find B'hala and the obelisk. (DS9: "Rapture")
