Right across the river from Philadelphia, a glitzy, five-bedroom manse in Voorhees, NJ, has hit the market asking $2.9 million.

Batten down the hatches! Along with luxe extras like a two-story pool house, a 42-seat bar, a soundproof movie theater, a DJ booth and a minicasino comes one super-special amenity: a bomb shelter.

“You’ll amaze guests with your 130ft long, solid concrete, underground tunnel. Yes, this artful and imaginative home has a bomb-proof underground tunnel!!!” brokers Agent06 exclaim in their description of the house. (Curbed first reported the listing.)

It’s truly party time at this spread, dubbed Alton Estate, which also comes with a huge pool, a full gym, a cedar-lined sauna, a 12-person Jacuzzi and waterfall-filled landscaping.

It’s perfect for doomsday believers with deep pockets.

But for those who think that the end of the world is a load of malarkey, the tunnel — the only part of the house that is unadorned — could be renovated into a wine cellar or a cigar room.
