A capacity-crowd at the last Euro 2012 venue to be completed after a raft of problems witnessed a lacklustre match with few memorable moments on a night which marked 100 days to go before Poland host Greece in the tournament opener in Warsaw.
Portugal midfielder Nani wasted a one-on-one chance to break the deadlock just before half-time while Polish striker Ireneusz Jelen failed to capitalise on a blunder from Portugal defender Bruno Alves.
"Today Portugal was at full strength, while we lacked a few key players. Overall its was a good debut of the venue," Poland coach Franciszek Smuda said.
Poland captain Jakub Blaszczykowski added: "With a team like Portugal there is no point in taking risks and we were just trying to be safe and we've played a good game all in all."
The 58,000 capacity arena is the largest of Poland's four arenas for Euro 2012, which it will co-host with Ukraine, and cost 1.75 billion zlotys ($562.3 million) - two-and-a-half-times more than any of the other three.
