Around 11:30 a.m. on Friday , calls came in to report a fire at the `` Benjamin Franklin Firehouse '' on the corner of Arch and Fouth streets in historic Old City Philadelphia . The firehouse sits on a block between the Betsy Ross house and Benjamin Franklin 's tomb , Richey said . No injuries were reported and great efforts were made to ensure that no historical landmarks were damaged by the fire , Richey said . The cause of the fire is still under investigation , but it is believed to have originated in a medic unit on the ground level of the firehouse , Richey said . `` There was significant damage to the firehouse and the apparatus floor area , and the medic unit looks like the engine area is completely lost , '' said Richey , who said the blaze was put out in nine minutes . Forty firefighters and eight fire trucks responded to the scene , including the engine 's own firefighters , who were out on a training mission when the fire started , Richey said . Efforts to repair the damaged firehouse are already underway , but it is unknown when the fire station will reopen , Richey said . Although the firehouse is in a historical area , the firehouse itself is not considered a historical landmark , and was built in the 1970s , according to Richey .
