Konta, who has the hopes of the home nation on her shoulders after men's champion Andy Murray went out in the quarter-finals on Wednesday, became the first British woman to reach the last four in almost 40 years when she beat Romanian Simona Halep.
Standing between sixth seed Konta and a shot at a first grand slam title, however, will be one of Wimbledon's most decorated daughters who has won five singles and six doubles titles at the All England Club.
The achievements of the 37-year-old Venus and her younger sister Serena are a remarkable part of Wimbledon's history, with the siblings having lifted the famous Rosewater Dish trophy in 12 of the last 17 tournaments, and Konta is full of admiration.

"I think what Venus and her sister have given our sport is absolutely tremendous. The way they've elevated women's tennis is truly inspiring. So I feel very excited and very humbled to be sharing the court with her again," she told reporters after her semi-final win over second seed Halep on Tuesday.
Waiting in the final will be either Spain's 14th seed Garbine Muguruza or unseeded Slovakian Magdalena Rybarikova, who meet in the other last-four clash.
Muguruza is looking to reach her second Wimbledon final, having been beaten by Serena Williams in 2015, while Rybarikova, the world number 87, is the lowest-ranked player for almost a decade to reach the women's last four.

Konta can only find the tramlines with a cross-court forehand before Venus benefits from consecutive net cords within the same point to move 0-30 ahead on the Briton's serve. Konta then double faults to give Venus three break points. Konta saves the first with a delightful drop volley before also saving the second with a cross-court forehand winner... but the sixth seed can't deny the American for a third time as she sends a forehand into the bottom of the net.
An unreturnable serve followed by an ace takes the game to 30-0. The pair then exchange groundstroke errors as Venus brings up two game points for a 4-1 lead in this second set... and she needs just one as Konta sends a forehand return well long.
Konta sandwiches a well-executed cross-court backhand pass with a couple of unreturnable serves to bring up three game points. The first one goes begging as she hits a backhand into the net before Venus also staves off the second with a forehand winner down the line. Konta then squanders the third with a missed forehand as Venus wrestles the game back to deuce. An unreturnable serve follows to bring up another game point... and this time she takes it with a backhand winner down the line.
Venus starts the game with a winning backhand drive volley before an inside-out forehand winner takes the game to 30-0. The American then sends a short backhand long but seals a hold to 15 as she follows up a Konta mistake off the ground with an unreturnable serve.
On reaching a ninth final at SW19: "I've played a lot of finals here. It's been a blessing. I couldn't have asked for more but I'll ask for a little more. One more win would be amazing. It won't be a given but I'll give it my all."
On the home crowd favouring Konta: "I thought the crowd was very nice to me. They could've been even more boisterous. I thought they were so fair. I know that they love Jo and she gave it her all today. It's a lot of pressure and I thought she handled it well but I think my experience just helped a lot."
On the winning moment: "She played so well. No point was easy. I just tried to climb on top each time to get another point and then it was done and I was just so happy."
On her opponent in the final, Garbine Muguruza: "We both play really well on grass. The last time (in the 2015 final) she played Serena so I'll have to ask Serena for some pointers. Serena's always in my corner and usually it's her in these finals so I'm trying my best to represent Williams as best as I can."
On how much she's missed Serena at Wimbledon: "Terribly. I missed her so much before this match and I was like, 'I just wish she was here.' Then I was like, 'I just wish she could do this for me' and I was like, 'no, this time you have to do it for yourself.' So, here we are!"
