On 28 April 1996 Mosta and Millbrae sealed an agreement by which they became twinned. Millbrae is a young city in the State of California, U.S.A.
It makes up part of the San Francisco area and here is found the largest number of emigrants coming from Mosta and their descendants. Thus while Millbrae is so far away from Mosta geographically, yet it may be said to be quite near to it due to the human bond that exists between the migrants and their Mostin relatives still residing in Mosta. In fact the distance between the two settlements is 13,047 kilometres or 8,109 miles.
Millbrae became a city with the right to its own City Council on 15 January 1948. The name ‘Millbrae’ is composed of two words, ‘Mill’ which is derived from the surname of one of the families which had much land in this locality ( the Mills family) and ‘brae’, which comes from the Scottish vocabulary meaning rolling hills. Millbrae is a small city especially when compared to its neighbour, San Francisco. It is considered to be a quiet, sunny and environmentally clean place as it is situated in the midst of greenery, fields and hills.
On the 50th anniversary of the establishment of Millbrae, the Mosta Local Council presented the residents of Millbrae with one of the component stones of the Rotunda belfry which had been replaced during restoration work. This gift is today found in front of the Millbrae City Hall with a plaque commemorating the event. In Mosta one of the main roads leading to the town is named Millbrae Avenue as an everlasting memory of this twinning with the American city.
Kien fl-2004 li, wara li saru diskussjonijiet bejn il-Kunsill Lokali tal-Mosta u l-Comune di Ragusa, belt ta’ importanza fi Sqallija, fl-1 ta’ Mejju 2004 ġie ffirmat ftehim ta’ ġemellaġġ. Kien fl-istess jum li fiha Malta saret parti mill-Unjoni Ewropea li l-Kunsill Lokali tal-Mosta ssiġilla dan il-ġemellaġġ mal-Comune di Ragusa. Il-ftehim ffirmawh is-Sindku tal-Mosta s-Sur Joe De Martino u s-Sindku ta’ Ragusa Dott. Antonio Solarino. Din iċ-ċerimonja saret fil-Mosta. Dan kien it-tieni ġemellaġġ li daħlet għalih il-Mosta. Ragusa, hi belt fin-naħa t’isfel ta’ Sqallija b’popolazzjoni ta’ madwar 70,000 ruħ. Hi l-kapitali tal-Provinċja ta’ Ragusa. Dan il-ġemellaġġ ħalla l-frott għax meta bdew il-proġetti tal-Unjoni Ewropea, il-Mosta daħlet fi sħubija ma’ Ragusa u ħadet żewġ proġetti taħt il-Programm Interreg IIIA Italja-Malta, wieħed kien CULTEXCHANGE u l-ieħor SMART. Fis-sena 2011, umbagħad, il-Mosta u Ragusa reġgħu ssieħbu u ħadmu proġett ieħor taħt il-Programm Italja-Malta, bl-isem ta’ ARCHAEOTUR li intemm f’Settembru 2013.
