Id-Dar tal-Barunissa which is located in the limits of San Leonardu in Żabbar, was originally intended to be used as a convent but was never utilised as such. The origins of the complex go back to the construction of a chapel in 1656 dedicated to St Leonard, from which the name of the locality stems.

Various additions were constructed, the latest being the ashlar stone wall and gates surrounding the garden, dated 1905. The garden was divided by means of elevated pathways and was irrigated through stone channels and troughs. The main focus of the garden is the intricately detailed nymphaeum at the end of the garden. The stone gates in the boundary wall may also have served as belvederes during the heydays of the complex.

Since the 1970s this house became known as Id-Dar tas-Soru owing to its use as a location for a local TV series bearing that title. The gardens have been recently taken over by a neighbouring farmer and covered with soil to be used as fields.

Mepa scheduled Il-Kunvent as a Grade 2 national monument as per Government Notice number 492/06 in the Government Gazette dated 6 June.
