Apart from the mayor and his deputies, City Council members receive no salaries and work on a voluntary basis. The longest-serving Jerusalem mayor was Teddy Kollek, who spent 28 years—six consecutive terms—in office. Most of the meetings of the Jerusalem City Council are private, but each month, it holds a session that is open to the public. Within the city council, religious political parties form an especially powerful faction, accounting for the majority of its seats. The headquarters of the Jerusalem Municipality and the mayor's office are at Safra Square (''Kikar Safra'') on Jaffa Road. The municipal complex, comprising two modern buildings and ten renovated historic buildings surrounding a large plaza, opened in 1993 when it moved from the old town hall building built by the Mandate authorities. The city falls under the Jerusalem District, with Jerusalem as the district's capital. 37% of the population is Palestinian, but in 2014 not more than 10% of tax revenues were allocated for them. In East Jerusalem, 52% of the land was excluded from development, 35% designated for Jewish settlements, and 13% for Palestinian use, almost all of which was already built on.
