An American who died in Lisbon's deadly funicular crash has been identified as Heather Hall, a mother of two and college teacher who was visiting Portugal from the US state of South Carolina.

An instructor at the College of Charleston, Ms Hall was among the 16 people who died when the Glória funicular crashed into a building on Wednesday. She was the only American killed in the accident.

Her family said Ms Hall "passed away doing what she did best — living life fully, boldly, and with a heart wide open to the world".

She worked as an instructor who specialised in literacy and special education and was in Lisbon to speak at a conference, the College of Charleston said in a statement.

Her family said Ms Hall was a first-generation college graduate who returned to her alma mater as a teacher where she was passionate about "creating inclusive spaces for children and adults with disabilities".
