Nativity scenes and other religious displays are generally permitted on public property if used in conjunction with the secular celebration of holidays.  However, a publicly-sponsored Nativity scene standing alone is unconstitutional.  Privately-sponsored nativity scenes displayed on public property are constitutional, even in the absence of other secular symbols.  Equal access is to be provided to competing interests/symbols.  Public acknowledgment of the private sponsorship should be posted conspicuously to avoid confusion or challenge.
